"Save when verifying or uploading" preference is not applied to "Export compiled Binary" action

When developing for the ESP8266, it often happens that the upload fails. Therefore it is easier if i export the binary and then upload it from the Command Line.

A small improvement point for this would be if there is an option to configure that the sketch is saved also before export binary.

The reason is that if the sketch is not saved, then a new copy is made which is compiled from scratch. A typical ESP8266 sketch is quite big and it compiles more than 1 minute. In comparison if i save and recompile then it takes "just" 30 seconds :)

Start by tracing the desktop IDE's "Export compiled Binary" action and the existing "Save when verifying or uploading" preference. The change is complete when exporting a compiled binary applies the configured save behavior, avoiding an unnecessary full recompilation when the sketch has unsaved changes.
