Allow explicit widths in project/platform symbols, part 2

Browse Source 
Added a Width column to the list in the project symbol editor.

Changed the local variable table editor and the project symbol editor
to use DataGrid instead of ListView.  This gets us easy sorting on
arbitrary columns.  The previous code was reloading the display list
after every change; now we just add/edit/remove individual items,
which helps keep the list position and selection stable.
