Build xbmc with all the available cores.
Added the helper file a new package needed to build xbmc.
Run xbmc at a higher priority

With this change the entire application is 'niced' up two levels.

You need to modify the file /etc/security/limits.conf by adding a line at the end:

    xbmc             -       nice            -15
Change installation path, session name and xbmc user directory name.

This patch changes the installation path (hardcoded) to /opt/xbmc-fm-master
adds a new session named XBMC FernetMenta Output to start the application,
in order to coexist with the packaged ad supposed stable version.

It changes the xbmc user working directory from .xbmc to .xbmc-fm-master
(Linux only), so to have a different configuration for the development
FernetMenta repository (branch master), with my patches.
