Q1 support patch

Q1 support patch (crafted by expanding hl support slightly), has one bug -
plugins/image/image.cpp had to be modified to use vfswad instead of vfspk3,
this breaks q3 support, however TTimo has said he will be fixing this soon (see
comment #12), so this patch will probably not be merged in until then.

Other notes:
1. the synapse.config for Q1 and HalfLife is identical, except that I use def
for Q1.
2. the synapse.config for Q1 and HalfLife need api "VFS" minor "wad" added to
the "map" section (this is explained in bug 796
http://zerowing.idsoftware.com/bugzilla/show_bug.cgi?id=796 )
3. constructing a proper GamePack for Quake1 is a bit complicated, I'm not sure
what to say about this at the moment (I have it working for myself), this is
just a patch for the code side of things.
