Feature: generic matchers (#1843)

Browse Source 
This commit extends the Matchers feature with the ability to have type-independent (e.g. templated) matchers. This is done by adding a new base type that Matchers can extend, `MatcherGenericBase`, and overloads of operators `!`, `&&` and `||` that handle matchers extending `MatcherGenericBase` in a special manner.

These new matchers can also take their arguments as values and non-const references.

Closes #1307 
Closes #1553 
Closes #1554
