Manually install texlive for travis-ci in order to support infographics build using the latext texlive environment

[jankapunkt]

Branch:
ci_setup

Log:
https://travis-ci.org/jankapunkt/latexcv/builds/256038205

Description:
On a local linux machine, the infographics test script exits with 0 and completes the tests. However, using travis completes all tests but the infographics test. It fails because travis (even on zeisty dist) still uses font spec to build font awesome, which requires either xetex or luatex. But this project should use only pdfLatex/pdfTex to build the files.

What needs to be done:
Get the travis config right, so that the infographics cv is built by using pdfLatex and not font spec. May be an issue with the packages loaded before the test - either there is something missing or a deprecated package is used.

seems to be a missing package: texlive-fonts-extra, will check on that

Found the problem. The travis environment is still not supporting Ubuntu 16.02 but the latest texlive-fonts-extra is required. This can only be installed manually.
