Some sceNpTrophy syscalls and few fixes

* Restored deleted functions in FuncList.cpp
* Fixed bugs in TRPLoader.
* Implemented some sceNpTrophy syscalls.
* Added sceNp headers (required for sceNpTrophy).
* Updated .gitignore to ignore trophies.

NOTE: Thanks to the new sceNpTrophy syscalls, RPCS3 can install the
trophy contents in dev_hdd0/home/00000001/trophy/. Remember this is
still on an experimental stage.
