Compile/Run on save

[mfornet]

When the main code is saved run the code Run the code and report status.

This should be optional, as some users might save too frequently, or might not want this issue at all.

Possible solution for frequent saving

Only run 1 time every X seconds. If saving was invoked at least once after last run and X seconds have passed run the program again. With this heuristic the program will be executed at most once every X but also will be run after last save.
