enable more codecs in debian package
put user DOCS in /usr/share/doc
add lua5.2 for Ubuntu
Merge branch 'master' of github.com:mpv-player/mpv-build
add libmpg123-dev to debian package now that the fix for precise is in 0.3.6

also add rst2pdf even though the new pdf generation didn't make it to
0.3.6. On git master, it builds the pdf manual (in
/usr/share/doc/mpv.pdf.gz). On 0.3.6, its just a few more packages
that can be removed after build.

Closes #29
oops: fix location of some docs in debian pacakge
update README.Debian now that mpg123 is enabled
add --ignore-missing-info for dh_shlibdeps in debian/rules to allow
linking against manually installed dependencies
enable gnutls in ffmpeg build to handle https:// streams
put myself in the maintainer field
and add to the copyright file
enable caca in the debian pacakge - in a silly mood
tweak debian build instructions

includes recommending dpkg-buildpackage over debuild (which does more
stuff that's probably not applicable to a local user build).
remove the trailing / from subrepositories in .gitignore
this allows them to be symlinks without making noise in git status
remove wrong pluralisation in README
move the ./update command to before mk-build-deps in debian instructions

This covers the case of changed build-dependencies in the debian package.
Don't use ffmpeg release candidates

The update script picked n2.2-rc2 over n2.2, which is very bad. Fix this
by ignoring tags that contain the string "rc".
debian: just remove old debian changelog stuff. the git log makes this redundant.
Update README.Debian
Remove customization note in ffmpeg-config

People edit this -> ./update stops working, unless the changes are
committed, which is not very obvious. They should edit ffmpeg_options
instead. There's a big section in the README about this.

Also, make mpv-config read mpv_config.
