This moves the CONST replacement up before we turn the elements into a
single string. The advantage is that we don't have to worry about
splitting the string properly to find the CONST names as the elements
are already split for us.t
The new dialogs includes 5 settings:
1. Flag to turn on Optimization (off by default)
2. Flag to strip symbols (On by default)
3. String for extra compiler flags
4. String for extra linker flags
5. Setting for max compiler processes (default of 3)
