TinyMCE 4.x plugin to later replace the tiny_mce (3.x) plugin (for now kept side by side). Notes:
a) tinyZenpage is working but with an (official) workaround to make the old 3.x API work. Needs to be figured out how to update that.
b) elFinder needs to be configured differently if it should work with 4.x. There is a tutorial on its site though.
c) There are no languages included (their naming convention issues)
d) The buttons currently are jumping because our css overrides the editor css here. To be fixed sometime soon.
