[OS-webwork] Escaping

[Pat Lightbody]

There are a few open issues with regards to escaping -- none of which all agree how it should be handled. Some want UI tags to escape, some want them not to. Some want the URL tag to escape, others don't. I am leaning towards this:   * UI tags, property, iterate, text, etc should all _escape_ by default * URL tag should NOT escape by default * All tags should have an escape attribute (true/false) * Possibly have global params in webwork.properties to override the two defaults (UI & URL)   What do you guys think?   -Pat
