Prevent assets from loading multiple times. Caused an issue where character count wasn't updated when having sections with multiple textbox fields.
Class 'invalid' inherits styles from Symphony core, overlays content in textbox field when reaching the character limit. Changed class name.
Using mb_strlen(, 'utf-8') instead of strlen() to account for special characters when checking content length.
Update return when no data for table view

Instead of return a blank when there is no data use the default return of 'None'.
This allows Symphony to display links if the field is set as the first entry and
thus in table view would have to be linked. When this was none no link was displayed
thus making the entry unreachable.

Return 'None' instead of nothing so that Symphony can correctly link to Textbox fields with no data from the backend.
