Template language should not complain on use of # symbol

[bruno]

Right now, if you have somewhere the symbol # in the template language (as e.g. in href="#"), you will see the following in the logs:

invalid expression: # must be followed by a EL expression or should be escaped.

Since this is so common, I don't think this should be reported. Same goes of course for other such symbols.

Similar issue as #50. Where report was about the $ sign.
