Bug 9172 - Move TinyMCE library outside of language-specific directory

This patch removes the TinyMCE library from its language-specific
location and puts it in intranet-tmpl/lib. The most recent version
of TinyMCE is used, and the files added have been limited to
those required for proper functionality of the editor.

Files omitted: documentation, examples, unused plugins.

To test, visit each page which uses the TinyMCE editor: News
editing (tools/koha-news.pl), library editing (admin/branches.pl),
and online help editing (help/edithelp.pl). The editor should
look and function as before.
