TAB-Navigation instead of Shift-Tab

[Siedlerchr]

Currently you have to use SHIFT+TAB to move from one field to another in the entry editor.

Attention!
SHIFT+TAB usually moves the cursor to the previous field; on the contrary, TAB moves to the following tab.

Therefore, I suggest to keep unmodified the behaviour of SHIFT+TAB, but to add the usual behavior of the TAB button.

This should be fixed in the latest development version. Could you please check the build from http://builds.jabref.org/master/. Thanks!

Checked right now v. 4.0 beta2 and working!

Many thanks!
