* csslint/csslint.c: did some fixes/cleanup here.
Make sure csslint --help shows a proper help.
* src/parser/cr-statement.c:
(cr_statement_dump): when a NULL statement is given, do
not dump anything, instead considering this as an error.
* src/parser/cr-stylesheet.c:
(cr_stylesheet_dump): give the possibility to dump
empty sheets, instead of considering this case as
an error case.
