Don't allow leading/trailing spaces in commands.

Trailing or leading whitespaces in commands
cause them to fail. For example "ls  " is an
invalid command. Show an error message to the user
when she tries to save such a command.

#315 - The pipeline label gets resolved.

* If a dependency material P1 ({material-P1}) was referred to by current pipeline P0 (with label ${material-P1}) and an upstream material pipeline P2 ({material-P2}, Triangle Dependency), and the order of materials was such that the resolution of material-P2 for the current pipeline happened before the resolution of material-P1, the name of material-P1 for pipeline P0 got changed and the resolution for the current pipeline label failed.

* The material name was getting changed during fan-in resolution. This fix restores the computed material config to actual material config after fan-in graph is generated.
