/**
* Does some local checking of a filename.
* If you want more specific filename checks (such as bad words, other blacklisted stuff) use the TitleBlacklist API.
*
* These checks are ignored when the TitleBlacklist API is available, since presumably they should be configured there instead, where it's
* possible to update them easily and higher-quality error messages are available.
*
* This is an incomplete rendering of some of the meta.wikimedia.org and commons.wikimedia.org blacklist as they existed on 2011-05-05, and
* ignores cases that are irrelevant to uploading new media images.
* - all regexes are case INsensitive by default
* - namespaces and File: prefix are removed since everything we upload is under File: anyway
* - noedit, moveonly, repuload is irrelevant
* - we can't check autoconfirmed-ness of users here, so we ignore it
* - Javascript doesn't have a standard way to access unicode character properties in regexes, so \p{PROPERTY}, \P{PROPERTY}, and [[:PROPERTY:]] have been changed when possible
* or the associated regex removed
