14425	(patch) Improve Wikipedia tag validators	nyurik	team	"Wikipedia tags need a few more validators with fixers:
* update the list of valid Wikipedia languages
* auto-replace language be-x-old with be-tarask
* auto-replace language cz with cs
* remove space before page title   (""en: Foo"" -> ""en:Foo"")
* replace ""_"" with spaces   (""en:Foo_bar"" -> ""en:Foo bar"")
* replace ""_"" with spaces   (""en:Foo_bar"" -> ""en:Foo bar"")
* capitalize first letter if it's not ""jbo"" language   (""en:foo"" ->  ""en:Foo"")

* double language link (""en:en:Foo"" -> ""en:Foo"")
{{{
  This part is not implemented because it requires regex backreferences in validators,
  which don't work for some reason:  *[wikipedia =~ /^([-a-z]{2,12}:)\1/] {...}
}}}

This patch also adds a few additional validator functions: trim, upper and lower (for completeness)"	enhancement	new	normal		Core			patch,wikipedia,validator
