JBIDE-18903 Refactor implementations of ITagLibRecognizer

Second contribution to refactoring. Interface methods changed
boolean ITagLibRecognizer.isUsed(ELContext context);
boolean ITagLibRecognizer.isUsed(IFile file);
IHTMLLibraryVersion ITagLibVersionRecognizer.getVersion(ELContext context);
Interface ITagLibVersionRecognizer is implemented by HTMLRecognizer
and IonicRecognizer.
We should to change the javadoc since we don't pass any version in this method anymore
