trajCutLTR needs revision

[Laurie Nevay]

the trajCutLTR cuts on the sqrt(x^2 + y^2). However, these variables are global coordinates which is likely not the intended function. This should be revised to local coordinates.

See BDSEventAction.cc ~line 264

This was introduced by Lawrence in commit 99314f9. Agreed that local coordinates would be better as that caters for non-linear machines too.

Fix Issue #223.
