* do not use stopwords in fulltext search
apparentyl there is a bug in innodb where including stopwords in a search causes the lookup to fail entirely.
e.g. innodb_ft_enable_stopword must be disabled when the index is edited (rows are added/removed)
* don't create a MATCH AGAINST search from empty search strings after sanitization
* drop fulltext indizes for locale zhCN
logographic languages need special treatment, which handling may differ by db provider
* use LIKE search by default for locale zhCN. Added config option to use fulltext if supported by db.
* split global.js into its components, so it can be reasonably processed by setup
* make reputation requirements configurable
* move Markup and Locale back into global.js (removed associated build scripts)
* extend Icon to display iconId in lightbox popup
* split Screenshot upload & management into separate endpoints
* move shared functions to manager classes
* cleanup javascript
* move test for config screenshot min size to cfg class
