Compiling on ubuntu 14.04 and qt 5.5

[lukasfischer83]

I needed some minor adjustments to compile it, in case someone finds this helpful:

quazip:

• unzip libs/quazip...tar.gz
• patch with: user@host:~/libs/quazip-0.7.1/quazip$ patch < ../../quazip-0.7.1.patch
• open in qt creator and compile (debug/release)
• adjust quazip .so lib path in libs.pri to the compile output path of step above
• adjust build path in scripts/build/lin-pre-link.sh to same as above

fonts:

• unzip fonts/open-sans.zip and copy all ttfs to font/

translations:

• open tra/eddypro_en.ts with qt translator and run file->release to create eddypro_en.qm
