the first 'major' change in this PR is to cache the generated event executrs from the ASM class, by doing this we only generate a single class for every method that we need an executor for, thus reducing the number of classes that are needed, especially in cases where plugins re/unregister events all the time. The second change is to modify the generated classloader map, generated classloaders are not held against the plugin itself but the classloader that the event is declared in, the implication here is that we cannot drop generated classloaders when a plugin disable, and so we use a guava weak-key'd hashmap, downfall here is that classes won't be GC'd until guava drops the generated classloader, however the first change should deal with most of the grunt.

Subject: [PATCH] Profile Lookup Events
|
|
|
|
Adds a Pre Lookup Event and a Post Lookup Event so that plugins may prefill in profile data, and cache the responses from
|
|
profiles that had to be looked up.
