Compiling buffers without files

Originally by @technobly:

There is a feature that I had planned to ask for that is supported on the Arduino IDE, where you can make changes to a file and compile and flash the unsaved changes to your arduino. This is useful for quickly editing the examples without having to find a place to save them, or to copy paste some code from the web to try much in the same way. Sometimes you just want to try something without saving it and cluttering up your hard drive with one more set of files.

If the way unsaved files was handled was something more like it makes a copy of all files in your project and all open unsaved files to a temporary location whenever you press Verify or Flash, it would be able to compile unsaved or saved files transparently.
