Map prefixes and suffixes

Common traditional naming conventions for maps for some Half-Life and Source games use a small prefix (often two or three letters) followed by an underscore at the beginning of the map name. For example "de_dust", where "de_" is the prefix and "dust" is the map name. In addition, some custom maps can be marked with unofficial prefixes, either to denote its nature or to brand it.

Todo: Add descriptions and prefix names for those who do not have any.
