[New Stuff] Updated editor,adding files procedure,and re-configured compiler

Hello there!

Until now you were not able to upload your old sketches in .pde format, even if they were compatible. Although .pde files are deprecated, we realized that this was a hassle, so we added support for .pde files for those with older projects.

Got confused with the compiler's excessive suggestions? Especially if you are not an engineer?
Well, we have now re-configured our compiler infrastructure to give you the exact info you need to debug and finish your projects faster, and nothing more!

We also updated the editor, in order to increase productivity when coding, by adding some features that help our users find and fix bugs in their code easier and faster.

You can drop us a line if your have any feedback, comments or ideas!
