add custom TextCtrl allowed to enter long integer with bounds checking

It's needed because wx.SpinCtrl supports only 'int' type. For UDINT
and (U)LINT long type is necessary.
These classes are intended for use server-side.
e.g. in a django view.py :
from pyjs.jsonrpc.django import JSONService, jsonremote
jsonservice = JSONRPCService()
@jsonremote(jsonservice)
def test(request, echo_param):
return "echoing the param back: %s" % echo_param
