angular.isRegexp is no angular function

[tilmanschweitzer]

The angular.isRegexp function seems to belong to a third party module: https://github.com/pbakondy/angular-typecheck

It should be deprecated and moved to another project or at least mentioned in the docs.

I neve realized thius method never exist. I do not why I have created this rule :D. I think we should deprecated this rule.

I will deprecate the rule for the 0.13.0 release, but keep this issue opened in order to remember than we have to remove it for the 1.0.0 release.
