Refine Lexers for parsing stray angled brackets; %Core.AggressivelyFixLt = true

Browse Source 
By default, the DirectLex and DOMLex behavior with stray angled brackets
varied a great deal due to their implementations. A little known directive
%Core.AggressivelyFixLt attempted to match DOMLex's behavior with DirectLex's,
but it was off by default. By turning it on by default, users now enjoy these
benefits, and performance-minded users can turn it back off.

Also, several refinements to stray angled bracket parsing was made. Specifically:

* DirectLex: Handle each left angled bracket individually, which prevents
  strange behavior as reported by eon.
* DOMLex: Iterate aggressive lt fix, so that stacked brackets like << are
  handled.
