gscreen -add code for a calculator dialog

Calculators are handy
gladevcp -offsetpage_widget -fix B axis column not being editable
gscreen -define some variables earlier so no error in Gmoccapy

Norbert referenced these variables earlier then I so got an error.
gscreen config -change the layout of industrial

This allows the onboard keyboard to show at anytime.
add a calculator launch button
other odds and ends to tighten up the display
gladevcp -fix offsetpage widget out of index error

When using entering data into a config that didnt start with
X axis and wasn't continous to the last axis (XYZABC) would
give an error.
This was because we excluded the extra axes letters in the variable.
The variable is used to convert axes letter to number.
now the variable always has all the axes so the lookup number is right.
gscreen config -fix axes buttons on industrial

some were buttons instead of toggle buttons
