#145 Evaluate Newer TinyMCE Versions

[Tim Parkinson]

LabTrove ships with TinyMCE version 3.4.8 as far as I can see.

But TinyMCE has been continuously improved since we integrated it into LabTrove.
The latest '3' series version is 3.5.10.
The latest '4' series version is 4.0.18

Can you do trial upgrades to both in turn to see if we go any faster or look any better
and have a look at the changelogs to see if there are any obvious fixes to any of our
outstanding issues and see if the upgrades break anything.
And document somewhere which variant of TinyMCE we use (vanilla or jQuery etc).
