Change email address detection in TinyMCE link plugin.

	- If link has a "@" and a ":", do not consider it an email address.
Add un-minified version of plugin.js file for link plugin.
Update build instructions to include media plugin.
Commit re-built minified JS.
Add all plugins to Jakefile.js in zip file.
Reason for this commit:
Split acceptance test was failing when TinyMCE detected a Split asset
key as an email address. Fix was to modify email address detection.
