Override -Selection Mode- & -Convert Selection- in EditablePoly/UnwrapUVW

This script override selection mode in EditablePoly/UnwrapUVW AND allow to Convert subobject selection to an another in EditablePoly and Unwrap

Hit 1 or 2/3/4/5 ==> go in vertex/edge/..() mode
Re-hit 1 or 2/3/4/5 ==> go in object mode and you can select another object!
I have added a line, with "Max modify mode", like this, if your are not in "modify panel" when you select an object and hit 1 to set vertex mode, the script go automatically in the panel "modify"

Install:
Go in Customize User Interface, Group "Main UI", Category "zOffTy Tools" and set
1 for epoly_vertex
2 for epoly_edge
3 for epoly_border
4 for epoly_face
5 for epoly_element
Sometimes 1 2 3 4 5 from "Editable poly" Group are not replaced automatically, so you have to remove them manually
Shortcut for Converting subobject selection to an another in EditablePoly and Unwrap:
CTRL+1 for epoly_convert_to_vertex
CTRL+2 for epoly_convert_to_edge
CTRL+3 for epoly_convert_to_border
CTRL+4 for epoly_convert_to_face
CTRL+5 for epoly_convert_to_element
