[svn r37545] Moved get_star_import_tree out of the DocStorage class, created 'pkg_to_dict'

function in docstorage.py and using that from apigen.py (to later simplify
py.test integration, and to improve testability). Simplified 'deindent()' a
bit, made the wrap_page use the filenames from the stylesheeturl and the
scripturls instead of having them hard-coded, some minor HTML/CSS changes.
