wip: group acl editing
fully operational
some fixing
Style tweaking
more tweaking
styling, bugfixing, remove-rule button
deleterule implementation
Properly preselect dropdown options
When creating a new rule, default to "grant"
acllist input validation
alert on errors rather than success
tweak wording on rules
clean up old group editing endpoints
Two more bugfixes

- input checking for new rules (clone(true) to copy data-input-validator)
- don't include the .first row when adding a rule
oops, the table always needs to be there
handle all stringlistinput add buttons
