New functions

Added cellSync module, implemented sys_spu_thread_group_join,
sys_spu_thread_group_suspend, added /dev_bdvd/ device, fixed default
values of analog sticks.
Fixed conflicts
RSX Debugger & cellFont improved

RSX Debugger:
*Better way to add name:value pairs to the tabs.
*Added some entries in the Settings/Texture/Lightning tabs.
*Experimental DisAsm.
*Support for previewing RGB textures (buggy!).
*Minor cleanups and improvements

cellFont:
*Added cellFontOpenFontMemory, cellFontOpenFontFile,
cellFontOpenFontset. They still need some modifications (e.g. bind these
functions to stblib/stb_truetype.h).
Merge branch 'master' of https://github.com/DHrpcs3/rpcs3
RSX Debugger, Mem. Viewer and module improvements

* Small cleanup in cellJpgDec and cellPngDec.
* cellPamf added to the project and a few test lines added to
cellPamfGetHeaderSize(2).
* Improved speed of the Raw Image Preview on the the Memory Viewer.
* Now you can click on the shown buffers / textures in the RSX Debugger
in order to see them in full size. More settings added to the tabs.
* Fixed cellFsStat in order to fix the crash aused by opening
directiories. The solution is really *really* ugly. Once vfsDir is
ready, I will replace it with something better.
