Now we have a mapping in EL validator between context variable names and resources that reference to them.
So if user changed a *.java with @Name("name1") we revalidate all resources which have #

{name1...}
But actually we don't need to parse whole resource again to find #{name1...}

. It's too slow.
Let's improove this one and keep references between each EL and variable name. Then we will be able to revalidate particular EL if context variable was changed.
It's won't require so slow parsing of each resource with referenced ELs.
