system:http_header currently works case-sensitively.

RFC 2616 ("Hypertext Transfer Protocol -- HTTP/1.1"), section 4.2, defines header field names as case-insensitive.

ThemeKey should respect the RFC and treat header names (but not necessarily values) case-insensitively.

For example:
host=blubb.example should match
both request headers:
myheader: blubb.example
and
MyHeader: blubb.example

That feature would cause some exceptions in the rule matching engine.
But it could already be achieved if you use the regex operator and the case insensitive modifier.
