Fixed #4444 Error in the template htm /usr/local/ispconfig/interface/web/client/templates/reseller_edit_limits.htm

- added limit for letsencrypt and directive snippets selector to client limits
- hide ssl tab if letsencrypt is selected

- removed most static content from scrigo

- cleaned up some javascript

- Added section toggle for client limits

- Resellers can use templates for their clients.

- Added fields to client, reseller and website to show when a record was added and by which user

Fixed: password match function blocked tabs incorrectly
Fixed: set focus on username input field threw an error if this field did not exist on a page

Removed template selector from reseller limits as templates are for clients only at the moment and a client template which gets applied to a reseller will convert the reseller to a client which is not intended. Templates for resellers will be added in a future version.
