 - Use module_Exists as appropriate
 - Rename module_FindName as module_Find

Don't free() a char variable when it is on the stack (in src/modules/modules.c SaveCache()) and be more sane about contents of psz_filename.

(Modules that would still depend on module_config_t are not going to like this, but it's not like you weren't warned a long time ahead)

Add argument to module_GetModulesNamesForCapability (and services_discovery_GetServicesNames) to also get the longnames.

Fix module_GetModulesNamesForCapability() and make it handle submodules properly (ie: the shoutcasttv submodule is returned as "shoutcasttv" instead of "shout"). This function (or its services_discovery_GetServicesNames(p_this) specialised version) should be used in interfaces, instead of the current code duplication.

XDG Base Directory Specification fix. I wasn't using the XDG_CACHE_HOME variable for the cache directory. Thanks to ILEoo for noticing.

On OSes other than Windows, Mac OS X and BeOS (so it's Linux) comply with the XDG Base Directory Specification version 0.6. The old configuration file (vlcrc) will be copied to the new location. Other data like caches will have to be rebuilt (the album art cache in VLC was new in 0.9.0 so it's ok to lose it). Closes #1267

(we had them because of the big vlc_symbol structure)

Add new module_FindName function to find a module when given it's name. Use this to fix the qt interface extended panel (video filters).
Change module_Exists to take the module name (and not short name) as parameter. Update the only known use of that function acordingly.

This is not strictly required, but helps propage fix for #1086.
