The set of regexes currently exported by TWiki::Func::getRegularExpression is unreasonably limited. You can currently only legally get a few character classes and the wikiword RE. There is a clear need to export other REs for plugins. The proposal here is to change the set of exported REs as follows. The italicised ones are new:

Name	Matches	Type
upperAlpha	Upper case characters	String
upperAlphaNum	Upper case characters and digits	String
lowerAlpha	Lower case characters	String
lowerAlphaNum	Lower case characters and digits	String
numeric	Digits	String
mixedAlpha	Alphabetic characters	String
mixedAlphaNum	Alphanumeric characters	String
wikiWordRegex	WikiWords	RE
webNameRegex	User web names	RE
anchorRegex	#Anchor_Names	RE
abbrevRegex	Abbreviations e.g. GOV, IRS	RE
emailAddrRegex	email@addressPLEASENOSPAM.com	RE

Rationale: these are all either useful for internationalisation, or or valid TWiki concepts that are already documented and are reasonable to export. Several are already unofficially used by plugins.
