Remove deprecated comet functions/functionality.
Drop deprecated Box apply.
Drop a bunch of deprecated stuff.

These are deprecated things that have no interdependencies
in the code, so removing them within the Lift codebase is
clean.
Drop deprecated S.??.
Drop deprecated LiftRules.docType.
Drop deprecated LiftRules.noCometSessionPage.
Drop deprecated JQuery1(3|4)Artifacts.
Drop deprecated LiftRules.servletAsyncProvider.
Drop deprecated LiftRules.*supplimental* header variants.
Rip out most JSONParser-related stuff in S/SHtml.

Still pending is a setFieldFromJSON in MetaRecord.
Rip out JSONParser stuff in Record.
Rip out JSONParser.

These were marked in scaladoc as deprecated; we'll backport a proper
deprecation warning to 2.6.
