THIS PATCH IS PRELIMINARY AND DOES NOT WORK.
It also needs some major cleanup and most plugins are not yet compiling. Going to need any help I can get here, but I'll be working on it.
-Removed "Remove All" button from rom browser config tab. There wasn't a stock gtk button for remove all and it didn't really seem necessary since you can select all of the directories and then click the "Remove" button.
-Removed unnecessary callback functions for about dialog, made about dialog not resizable.
-Added file filters to load dialogs for a more polished file chooser.
-Removed chdir to the config dir (~/.mupen64plus) from setPaths function. This was a hack to get around the fact that plugins were looking in the current working dir for config files. I've since fixed that issue, so the chdir is no longer necessary. Plus, the chdir was causing the file chooser dialogs to default to ~/.mupen64plus, which could be confusing to a user.
-Separated LIRC functions into new lirc.c file so they can be used in gui or nogui build.
-Added pause/continue functionality to LIRC.
-Made it so LIRC commands work while emulation is paused.
-Added wiki page on how to setup LIRC for Mupen64Plus.
-Fixed minor bug with g_EmulationRunning (it was being set to 1 during stopEmulation).
