Caching package information

[Maximilian Wuttke]

Hi,

The "C-c RET" completion for `\usepackage` caches the available packages
into a variable (I think `TeX-global-input-files`). However, this list
is not saved to the disk, and if I restart Emacs, the packages have to
be rescanned, which takes some time (ca. 10 seconds on my computer).

It would be a nice feature to save the packages (and of course also
provide a command to update the list). But my Emacs Lisp skills are not
good enough yet to implement this feature.

PS: AUCTex is great! It was one of the reasons why I switched from vim
to Emacs. :) I've already written my bachelor's thesis and a paper with
Emacs, and now I'm writing my master's thesis.
