Fix Eclipse Wizard Button Labels

I admit this is a minor issue, but still worth mentioning.  The current labels for the "Build for Device" and "Export" wizards are confusing.

Currently, clicking "Finish" builds the files and "Cancel" closes the wizard whether or not the build was successful.

I would expect to click "Build" or "Start" in order to initiate the build process (not "Finish").  Then, I would expect to click "Finish" or "Done" to close the wizard.  I would only expect to click "Cancel" if I didn't mean to open the wizard in the first place, or if something went wrong and I need to close the wizard to fix the issue before I can build.

Maybe it's just me, but I've unintentionally re-built my project a couple times now because I forget that "Finish" doesn't do what I expect it to.
