Use tikzpictures instead of graphics. 

I've altered your approach: Your `resume.tex` now includes the source of the tikzpictures and makes use of them to create the images. By doing so there is no more need for `githubsym.tex` or `linkedinsym.tex` to be compiled separately. I've also changed the .intexration file [and now your repository compiles](http://intexration.jonasdevlieghere.com:8000/log/JDevlieghere/resume/resume) with InTeXration.
