Don't re-compile on upload if sketch hasn't changed since last compilation.

[GoogleCodeExporter]

What change would like to see?

Loading to arduino split into 2 steps.
Step 1 would compile (a bit like the verify, but would save the resulting 
files) and step 2 would load to the chip. (if no verified compiled version of 
the sketch exist it would compile one and load it to the chip. But one exist it 
would not re-compile but load the existing verified one.)

Why?
When loading big sketches on multiple chips, it take a while to compile and the 
load to the chip. If there is no changes to the sketch....why re-compile it 
every time?

Another benefit is that users wanting to load sketches whit something else then 
the IDE would be able to easily create compile files to a permanent and known 
location.

I think this is basically handled by the general changes to only recompile 
changed files.
