Update gitignore to ignore x64 folders.
Remove unused include and very small refactoring.

Unused include in unself.h, ELF.h.
New line after an if to enable debugging.
Rewrite strange boolean expression in ELF.cpp.
Change ModuleManager::init function.

First step to help refactor Module management.
Add every module in the static ModuleInfo list. Module without id are assigned
to 0xffff.
The init function is called after constructor and take a pointer to Module
as an input.
This pointer is used to set the Module's global pointer in its file.
