Make strip_html strip tags spread across lines
fix example servlet
Make strip_html filter strip contents of style tags
Added tests to verify that {{ 'now' | date :'%Y' }} and {{ 'today' | date :'%Y' }} work.

In the case of Ruby 1.9.3, 'now' is no longer parsed.  For safe
measures, I've added 'today' as well.

typo
Use array instead of Hash to keep the registered filters

1.8.7 compatibility fix

In Ruby 1.8.7, Hash does not preserve insertion ordering as Array does.
This could cause a problem when registering filters which depend on others and
the registration order is important.

So, the @@filters variable was changed to array where the order of the filters is
the same as the insertion order.
