Hi This is my patch to try and standardise the input boxes for numbers .
Now spinners are selectable in main options screen. You have the ability to use the mouse wheel over an edit box to increase/decrease the numeric value. Also by holding CTRL while using wheel it will change amounts by minor grid line setting and Shift will change by Major grid setting.
Also does checking for valid numbers internally so should not get invalid number warning pop up. Still needs some changes to allow float values to be allowed where make sense (some have been changed) Rather than nearly all integers only. Also rollover hints need going through. Put up this version to see if like and if any glaring errors I have missed.
