Fix deploy

Bump to v0.5.0

Bump to v0.0.5

First version with support for --relative.

New alpha release

Still not production ready.

First version published to pip.

Major improvments:

* Support auto-summation of extensions with '.ext1+.ext2' syntax. Useful for
  e.g. '.c+.h'.

Minor improvements:
* No need for --filter any longer, just pass the .exts directly as args
* Add --list flag that lists all available extensions (in the first commit)
* Default to top-three extensions instead of complicated MIME logic
* Include git SHA1 in --version
* Stop spawning 'git log' child process, use git2-rs directly instead

Feature release. Flags added:

* --filter
* --min-interval (renamed from --interval)
* --max-rows
* --benchmark
* --debug
* --disable-progress-bar
* --all-parents

Use --help to get more info.

Performance release. 100 times faster than 0.1.2 due to git2-rs.
