#1 Autosizing columns by double-clicking right edge of column header

[Mark Livingstone]

At present, if you double click the right hand edge of a column header, it sets the column width to the width of the column header text (normally a single alphabetic character.)

I intend to modify this to the normal behaviour where it sized the column width to the size of the widest row of text in the column.

Eventually I foresee this being like other platforms where you can select several / all columns and autosize them in one click.
