Page view/preview broken by content filter

[gfowley]

The Gollum wiki content filter agressively blocks display of anything that might be an HTML tag, Javascript, CSS, etc...

This defeats purpose of this project which is to host code examples that may contain text that could be interpreted as HTML, etc...

No data is lost or changed, this is a view only problem.

For example a Ruby sub-class definition:

def SomeClass < ParentClass
  ...
end

This may be successfully edited and saved, but is agressively filtered such that everything including and following the '<' is not displayed in view/preview:

def SomeClass 

Will need smarter content filtering and/or input escaping ?
