Coding style: removed trailing white spaces.
Updated Maven plugins:
dependency plugin version 2.8
war plugin version 2.4
MathJax is no longer loaded via CDN and is instead directly included.
Coding style:
Added white space between function keyword and parenthesis.
Fixed inconsistent indentation.
Removed unnecessary semicolon.
Removed undefined parameter from openMobileSession method call.
Added value for radix parameter of parseInt to prevent problems with
different browser implementations.
Fix: appContainer is now correctly hidden if resolution requirements are
not met. This should slightly increase performance on window resizing.
