Fix for memory leak in c:set

This would be a problem for all branches when a user still uses the old 1.0 tag
libraries.

Patch attached to refactor SetSupport to defer evaluation of the expressions
until needed allowing only the attribute values to be retained (per the spec).

Patch also switches to using the JSP container's EL evaluator and pre-parses
the expressions (avoiding reparsing if the container is pooling tags).
