libobs: Add macro for default module locale 

These macros are used as easy helper functions to load/unload module
locale that's based upon the text_lookup system.  You simple place the
OBS_MODULE_USE_DEFAULT_LOCALE macro once in the module, call
OBS_MODULE_FREE_DEFAULT LOCALE in obs_module_unload, and then
call obs_module_text anywhere in your module where you need to look up
text.

By default, it will look for a locale directory in your module's data
directory, and look for language files within it (INI locale format)
