FFmpeg: reenabled curiously disabled logging suppression during thumbnail generation/media info extraction
CG commands: avoid logging stacktraces for user related errors, but return 404 CG ERROR instead

#222 Modified html_producer so that Caspar ticks the web browser. The javascript function onEnterFrame() must be implemented in order to achieve lag-free motion

BUG FIX: FFMPEG Producer. When using LOABG with AUTO, and a SEEK or LENGTH parameter was supplied. The frame count calculation was incorrect and could result in 0.

Moved framerate calculation from CLS/CINF to thumbnail generation time for each file. A new "database" media_info.csv will be created under the thumbnails folder containing the information.

Publish audio levels via osc. dBFS and pFS levels are provided. I am not sure of performance implications so perhaps this needs to be a configurable feature.

Patched SFML to not sleep so much in SoundStream.cpp (changed to 10 ms), which makes the oal consumer work as well as before the change to static linking against SFML. And therefore removed portaudio and reverted oal consumer to previous implementation.

No longer render flash frames as fast as possible, but paces the rendering to allow for time based (vs the preferred frame based) animations to be rendered as close to correct as possible. It will still be incorrect during buffer-recovery, but not during initial buffer fill.

Allow ogl window to be borderless. I found this useful in integrating a "preview" window into a client app. The client app can look for the window handle via it's name and then set it to stay on top via win32 api.
<borderless>true</borderless>
or
ADD 1 SCREEN BORDERLESS

Removed incorrect usage of av_interleaved_write_frame (for the version of FFmpeg we use) for flushing frames. It seems like flush support was added later.

Flash producer
- globally serialize initialization and destruction of flash players, to avoid race conditions in flash.
- changed so that the flash buffer is filled with flash player generated content at initialization instead of empty frames.
OSC
- merged OSC improvements #152 made by Robert Nagy up until commit https://github.com/ronag/Server/commit/bae86d21f1569b4b7ac1e08c024d62f389efa57e
- enclosed multiple OSC messages in the same UDP packet inside an OSC bundle to comply with OSC spec
- ensured that UDP packets are not too big (causing fragmentation, and errors on OSC receiving side)
- removed use of Microsoft Agents library which seemed to be the cause of running out of memory after a while. Now everything is done synchronously instead (without support for multiple targets, just a single target (parent) for now).
CG commands that expects an already running flash template no longer starts a flash player with a template host just to say "no template running on layer". Now only CG ADD and CG INFO creates a flash_producer/flash player if one is not already running on the video layer.
Huge performance impact detected with chroma key support (even though not in use for a layer) in image shader. Straight alpha output support also adds a small overhead (even when not in use), so just like with blend-modes it is now conditionally compiled in the shader, and turned on in the configuration file.
New <mixer /> element added to configuration for turning on mixer features that not everybody would want to pay for (performance-wise). blend-modes also moved into this element:
* Created custom decklink allocator for reducing memory footprint.
* Made sure that more threads have the unstructured exception handler installed (avoids crashing the entire process in case of access violations), and thread naming for more threads.
* Ensure that if an exception occurs while rendering the diagnostic window, the window is closed instead of it stopping to respond to window events.

#155
Fixed problem where SFML stops calling SoundStream::OnGetData when too few samples are returned. This problem seems to have started after the change to static linking against SFML. The current solution is to collect the samples of more frames (3) before returning sample data. This unfortunately adds a 2 frame delay on system audio, but solves the choppyness.
