Revamp of Java completion engine - use JDT's CompletionParser to parse source.
Use CompletionParser from Eclipse to parse incomplete, edited tree and
find node to complete. It also runs a Resolver to resolve types
and create type bindings, so when JavaCompletionParser is called back
all type informations should be in place. Now it supports completion
for types and variables. More will come in next commits.
