Pymacapp

- added: pymacapp.versioning.VersionLocker. This feature allows you to set a version (an unlimited-length string of non-negative integers delimited by periods ('.')) and pymacapp will store the version number in a file whenever its .lock() method is called (this is useful so that you can decide when to lock the version (i.e. do not lock until after the app successfully builds, successfully packages, etc.)).

- added: new coverage for py-makespec (included with pyinstaller)
- deprecated: App.setup(...); see below
- added: App.config(...) to use new coverage for py-makespec

- bug fixes
- moving some subprocess commands from subprocess.Popen(...) to a custom function which uses subprocess.run(...)
- updating README

- relocating custom commands (from pymacapp.command import cmd) and moving to beta
- removing: Resource feature introduced in 1.2.0

Patching release 1.2.1.

Adds an alpha feature: custom commands, natively in python.

from pymacapp.custom import bash
bash(...)

The bash function takes a list of strings. To run cd ~, you would call bash(["cd", "~"])
