Some new verbose error checks for sound and video systems.
StreamSound error: preparing fading_tests test to highlight error
StreamSound error: same issue confirmed for WAV sounds
StreamSound error: fixed, was caused by 'repeat' logic.

Playback repeat logic inside SSoundSource::update() function was misplaced.
The idea itself was wrong, and playback repeat handling was moved one level up,
into the SoundManager. More details can be found in MantisBT issue #355.

These changes make the restart "dead-time" between playbacks longer.
If a playlist is created containing a single, looping sound with no silent time
(like the water sound of the current fading_tests test) then the transition
between loops can be noticed.
In such scenarios direct use of the SoundManager is recommended. Check "NOTE"
in lines 418-422 of src/tools/tests/sound/fading_tests/SoundTest.cpp
in this commit.
SoundSystem: loading sound resources with our own ResourceHandler.

To load the sound files into the SoundSystem, now we use our own resources
managing system, instead of depending directly from Ogre::ResourceManager.
The "loadSound" functions from SoundHandler and SoundManager
now take a reference to a (properly configured) rrh::ResourceHandler.
Also, minor functional was added to rrh::ResourceGroup and rrh::ResourceHandler.
SoundSystem: unification of sound tests, following MantisBT issue #363
Some changes to the packet request system of the video player. Runs 720p video prety smood, have to check with 1080p ones.
Fixing an issue in the ogreWidget, we was saving the logs into the resources.cfg file
