- Added build helper-script.
- Updated build helper-script to include "make" for full compiling.
- Added patchset files.
- Applied first patch:
  * Fixed commandline executable (was lacking the new arguments added to
  the GUI version)
  * Translated some comments from French to English.
  * Improved wording of some text output.
- Renamed build helper-script to "compile.sh".
- Updated and set version number to "v2.0.0".
- Updated credits.
- Changed default threshold to 75 (was 60).
  The value 75 has been used on several hundred recordings of real-life
  archive material and was considered to be an effective default value.
- Added new option: embedding of video timecode in graph images.
- Added cmake install routines. Now shotdetect can now be installed using "make install".
- Added package description (description-pak) for "checkinstall".
- Added git revision SHA1 to be included in version string automatically.
- Added "GetGitRevisionDescription" cmake modules.
- Added vim swapfiles to ".gitignore".
- Changed color settings to be configurable per graph.
- Started changing color handling for adding additional graphs.
- Removed unused code (empty functions, etc).
- Removed leftover debug output messages from previous change.
- Fixed and added comments.
- Preparing for YUV graph output.
- Separated collecting color values and threshold detection.
- Preparing for YUV graph output.
- Added generic pixel-color struct.
- Unified graph image variable names (preparing for additional graphs).
- Completely separated colors of individual graphs.
- Added YUV graph (WARNING: values not verified yet).
- Minor cosmetic changes and additional comments.
- Small changes in color graph drawing: Made it easier to read.
- Switched AVPicture buffer handling from manual to ffmpeg's
  routine "avpicture_alloc". This should make it easier to support
  multiple pictures for multiple graphs for easily.
- Fixed using wrong buffer for YUV graph.
- NOTE: known bug = YUV graph is currently only functional with some videos.
- Renamed YUV label to YCbCr.
- Changed shot-detection algorithm to detect changes between full-black
  and full-white, or other RGB-extreme changes (R->G, G->B, ...).
  Tests on real video material revealed no regression, but rather just
  a more reasonable output.
- Added option to enable/disable each color graph separately.
- Disabled creation of YUV graph, because it's still not working
  reliably.
