Add option for excluding files from uploading as discussed in #18.

Can we have tests? It's a really big chunk of added code. It would be good if you could actually demonstrate this format is, in fact, equivalent to Git's.

Sub.
(Side note: aff413e looks intresting regarding testing, but we might want to prefer unit testing, here.)

Unfortunately i thrown away my tests when I was writing this separatly and then moved only the code…
However after reading glob manpage I realised I haven't solved matching slash within brackets, eg. [/], [!0], [.-0] and I don't see any way how to solve this in current implementation. I can push tests for the rest but there is probably no point without solving this first.

Since I can't resolve that within this code I am closing this pull and will open another with fixed code.
