Allow commas, spaces in pad names for net-ties 

Net tie groups are currently separated by comma.  But comma is also an
allowed, albeit rare character for pad names.  To allow pad names with
commas in net tie groups, the group definition must be escaped with a
forward slash for commas (and forward slashes).

Pad 1,2
Pad 2,3

Net-tie group "1\,2,2\,3"
