[release] pagure: 0.1.30

[Pierre-Yves Chibon]

Good morning everyone,

There was a couple of last minutes bugs on pagure that I didn't want to carry
all the way through freeze, so here is another (bugfix) release: 0.1.30

The changelog:
* Tue Oct 13 2015 Pierre-Yves Chibon  - 0.1.30-1
- Fix error received by email by checking the right variable if it is a git tree
  or a git blob
- Unless we explicitly accept all images tag, always filter them (fixes
  attaching images to a ticket)

Happy hacking,
Pierre
