Adding MathJax and XyJax to the project
Very preliminary tag preview (i.e. parsing the LaTeX)
Toggle between code and preview
Better previewing
More previewing capabilities
Cleanup of the previewing code
Improved the previewing code (slightly less awful code, checked tons of side cases
Added information on how to install XyJax

And fixed a really silly mistake
Fixed link parsing and made the code/view toggle a bit bigger
Merge branch 'xyjax' of https://github.com/pbelmans/stacks-website into xyjax
Undid the rewriterule mess in tag.php
Made the toggle more visible
Fixed the too greedy \ref{} parser
Parsing \url (in a rather greedy way, might want to look into that
Fixed issue in get_directory() in config.php

The default should be the version based on interpreting `$_SERVER$, not the hack necessary at some point on a test location
Addresses issue #1, don't assume \relax when parsing .aux
Added missing backslash in SheafHom parsing, fixes #5
Updated README.markdown, added a remark on pulling submodules which closes #3
First draft of sectional navigation on tag page, as requested in #4, also added previous and next tag navigation on top of each tag
As per #4 the section navigation is now also at the bottom (and replaces tag navigation)
