Check both directions for project/platform "nearby" matches

Browse Source 
If a symbol is defined at <addr>, and we counter STA <addr>-1,Y,
we want to use the symbol in the operand.  This worked for labels
but not project/platform symbols.

Also, fixed a crash that happened if you tried to delete an auto
label.
