Remove support for escape characters from glob patterns

I thought it'd be nice to ensure we could represent any character in the
patterns. However, this isn't required (as the client only uses
alphabetical class, method and field names). Furthermore, the period
character is already unusable in class names due to the MemberRef string
parsing.
