disable next phase button after user edits

[uxmal]

After a user edit - especially after changing a function signature - Reko will be in a inconsistent state. It is not easy to reconcile this inconsistent state as it would require an analysis from scratch.

Instead, after a user edit, the next phase button will be disabled.The restart decompilation should keep all user edits and restart the process anew.

Can we add a "Re-Analyze" button or something instead of doing a restart to the whole project. This option for example is available in IDA Hex-Rays and you would only need to re-analzye the project instead of restarting it again. Does that make sense?
