Describe the request

If no source file is changed since last uploading, there is no need to build the sketch again. The Arduino IDE can just re-use the firmware from the last build.
Users can still start a build by clicking "Verify" button.

Describe the current behavior

When clicking "Upload" button, the Arduino IDE will start a new build even if all source files are not changed.
