Fixed Bug

Fixed:
If there is a javadoc above a method, the folding button disapears
 When there are multiple nested if statements, only the first foldable
regions is recognized.
 Sometimes a return/contuine gets a folding button -> I think when the
return is in a if stament
 When a while/ if stament or something else is in a try/switch block,
they dont get a folding button
