The 'groups' column filter (select input) causes a Java Heap error in wikis with large amounts of groups #49

Because of the type of the groups column ('groups': {'type': 'list',`), the livetable macro generates the select filter which is causing problems when the wiki has a huge number of groups (e.g. 100K) and all of them are loaded into memory to be displayed as select options.

Changing the type to text keep the column without the problem filter. If we want to keep the filtering helper, the select could maybe be replaced with a suggest text input, showing suggestions based on the user's input.

The screenshot is from an older version, but the problem is present in the latest version as well: flash-messages-manyGroups-javaHeapError

suggest type is available since 9.8. We should use it.
