ZX: update .app

zx update .app

Keeping the ebin/*.app file up to date with module changes can be a bit of an annoyance, especially with large projects involving large numbers of modules or during a major refactoring. For convenience ZX provides an "update .app" command that will update this attribute for you.

Note that most of the time this command is unnecessary, as the same process occurs when you run the zx package ProjectDir command or use ZX to dialyze a project. Attributes other than 'vsn' and 'modules' found in the .app file should be maintained manually, as mentioned on the create project page.
