Merge lp:~hannes-hochreiner/jessyink/pdf-export into lp:jessyink/1.x

[Hannes Hochreiner]

[Hannes Hochreiner (hannes-hochreiner)]

PDF-export seems to work now on all platforms and is therefore ready to be merged into trunk.

[Hannes Hochreiner (hannes-hochreiner)]

Worked fine in my tests.

review: Approve (tested on windows and osx)
