- Load of plugins from the ms
- Changes in the HEN core:

 * Fixed a bug in the loading of big user prx's, that affected a plain prx of socom2 umd, and some
   homebrew prx's.

 * Bypassed a crappy $ce protection that prevented the umd to be mounted if the application was run from
   the memory stick

 * Usb mass storage couldn't be loaded by homebrews in non-devhook version because semawm.prx is sign checked.
   HEN now applies the algorithm to reverse the sign check, letting this and the rest of firmware
   modules to be loaded by a homebrew.

- Added a SDK for SE-C/HEN-D. (in a separate download)
