Add support for the filenames generated by KiCad by default

[Tim 'mithro' Ansell]

By default KiCad doesn't use the Protel names, instead all the files end in .gbr and it uses B.Cu and similar.

Example;

-rw-r----- 1 tansell eng 135617 Jul  3 21:40 dp-aux-intercept-B.Cu.gbr
-rw-r----- 1 tansell eng   3538 Jul  3 21:40 dp-aux-intercept-B.Mask.gbr
-rw-r----- 1 tansell eng    701 Jul  3 21:40 dp-aux-intercept-B.Paste.gbr
-rw-r----- 1 tansell eng  42262 Jul  3 21:40 dp-aux-intercept-B.SilkS.gbr
-rw-r----- 1 tansell eng    497 Jul  3 21:40 dp-aux-intercept-Edge.Cuts.gbr
-rw-r----- 1 tansell eng 181651 Jul  3 21:40 dp-aux-intercept-F.Cu.gbr
-rw-r----- 1 tansell eng   3831 Jul  3 21:40 dp-aux-intercept-F.Mask.gbr
-rw-r----- 1 tansell eng    989 Jul  3 21:40 dp-aux-intercept-F.Paste.gbr
-rw-r----- 1 tansell eng  51315 Jul  3 21:40 dp-aux-intercept-F.SilkS.gbr
-rw-r----- 1 tansell eng   9324 Jul  3 21:40 dp-aux-intercept-In1.Cu.gbr
-rw-r----- 1 tansell eng   9324 Jul  3 21:40 dp-aux-intercept-In2.Cu.gbr

Can you ping this issue when you have deployed it on gerblook.org?
