Optimization for aliases

Optimized AliasAdd() and AliasGet() by avoiding the usage of

Tcl_SetVar2Ex() and Tcl_GetVar2Ex(). This change improves the

performance of AliasAdd() by ~20% and AliasGet() by 10%.

Strangely, Tcl does not provide an interface to the

Tcl_Obj-based TclObjUnsetVar2(), which is used internally

by Tcl_UnsetVar2()), such we could also avoid the latter.
