Detect jquery scripts in templating
Merge pull request #317 from kp52/develop

Update icons sprite
Ensure jquery core added via normal JS API functions is not added again.
Move jquery noconflict call to be always after the jquery core file.
If jquery core file is set in the templating, not the API, this option now has no effect i.e. the templating will take precedence..
Omit jquery core if config option is empty
Merge branch 'jquery' of github.com:ClipperCMS/ClipperCMS into jquery

Conflicts:
	manager/includes/document.parser.class.inc.php
Remove noconflict code from regClientJquery (reinstated in error)
Disallow remote jquery core files for use in manager - use default local file if specified.
Also ensure that the local file exists if not the default jquery file.
