Load and Save

I've added (save, save all, load & load all) menu times.  My usuage typically starts from eclipse IDE - so its very different from using the UI all the time.  Gael is helping me with some cleanup (already fixed up Arduino oscope & pins) ..  

Working in the UI I find trying to get back to the feature I'm testing can be laborious (vs in eclipse it typically is just adding code to the main function).   There has been good and bad from trying to save the state of MRL.  It's not "easy", at the same time its sometimes very desirable.  So I've made these menu items to allow users to do want they want.  

For example if I create a mega Arduino service - set the ports, and Arduino IDE Path, I don't want to go through the same process of configuring all these parameters ...

Additionally on the arduino page I see the Path field is scrunched so its not visible, and the Upload MrlComm - is borked ..

On the good side the Open in Arduino IDE does work (Yay!) .. perhaps solving this issue is removing the Upload MrlComm button...
