Disable the menu-bar-mode, tool-bar-mode and scroll-bar-mode early on

Add /usr/share/emacs/site-lisp and
/usr/local/emacs/share/emacs/site-lisp and all their sub-directories
to the load-path so I can use modules from both Emacs from the
official repository and the self-compiled one.
This should be done both when compiling the elisp file and when loading it so it doesn't complain about missing modules and such.

Defer loading my theme until after emacs initialization. This is
