expect(object).toBeSymbol() & toBeWellKnownSymbol() & toBeCustomSymbol() & toBeSymbolFor(string)

[jrencz]

It's related to #43 - Symbols may be matched as well

toBeWellKnownSymbol should pass well-known Symbols and toBeCustomSymbol (any hint on a better name?) should fail then a well-known symbol is passed.
Well-known symbols exist as properties on Symbol host object.

Thanks @jrencz, I'd need a lot of input from you on this as I've not used Symbols.

Thanks again for raising this @jrencz but I've decided not to add matchers for Set etc. A new project such as jasmine-set-matchers could be useful to people though if you decide to take it on.
