Added module ImportParser and new stuff from DMD2.008.
Moved ImportParser from module Parser to its own module. Added a few methods
from class Parser and simplified them. Now protection attributes are taken into
consideration as well.
Added class TemplateThisParameter. Adapted TypeofType so that typeof(return)
can be recognized.
