[Mono-list] Parse methods

[Miguel de Icaza]

Just a quick update:

	Tonight I did hack the Parse (string s) methods for int, uint, 	long,
ulong, byte, short, ushort and sbyte.  A lot of copy
	pasting in there ;-)

	But the general idea I had here is that the Parse (string) 	method is a
very simplistic implementation and thus can be
	accelerated by not having to care about all the various settings
	permitted for the full blown parser.

So we still need the full blown parser ;-)

Miguel.
