adding .gitignore public/uploads
minifier.css isn't used
only need one "meta/css done" message
making the loading sequence less verbose

in particular, the js stuff all happened sequentially at the same time
so there was no need for multiple messages
commenting out the reconnection messages, it's annoying if you have 500 users online

not sure if we do need it though, so just leaving it there for now
closes #2244
much faster sitemap

no need to load all the data, when we only use slug and lastposttime
doing some reshuffling in public/src

public/src/admin and public/src/client; also some cleanup in
src/meta/js, no need to filter out admin files anymore
... not sure why that didn't all go through in one commit

removing leveldb from our dbal

a) It isn't being maintained, especially not by me
b) I haven't seen anybody actually interested in this db software so
there's no real point in supporting it unless we have a few people who
are interested

If you ARE interested though - please contact me and we can figure
something out in future :)
