[Patch] regex in key conditions doesn't allow comparisons

[naoliv]

It seems that regex in key conditions [6547] doesn't allow comparisons.
For example:

*[/^source/ =~ /.*,.*/] {
        throwOther: tr("you should use ;");
}

gives

org.openstreetmap.josm.gui.mappaint.mapcss.parsergen.ParseException: Encountered " <REGEX> "/^source/ "" at line 512, column 3.
Was expecting one of:
    "set" ...

This syntax is not supported at the moment.

Any objections for yet another key/value/select/feature? :)
