Module install directory

Line 107 of the editor_plugin.js file appears to be assuming that the TinyMCE module is installed in the modules directory, and not as we have in the sites/all/modules directory. For us this isn't a problem as we have clean URLs enabled, hence the resulting URL http://example.com/sites/all/index.php?q=easylink/load gets rewritten. However, for users who don't have clean URLs installed, this could well be a problem. Adding the following below line 107 should fix this.

base_url = base_url.substring(0, base_url.indexOf('sites/all'));
