More templates

The pycommand init script is removed and is included in the pycommand package itself.
To auto generate scripts from templates, from now on use:

python -m pycommand init

Added

• Full templates can now (also) be auto generated
• CI testing for Python 3.5 and 3.6

Changed

• The code is split up into several modules and pycommand is now
  distributed as a package rather than a single module. The public
  API does not change however, all relevant members (CommandBase,
  run_and_exit) that are now placed in pycommand.pycommand are
  exposed through __init__ and therefore are still available as
  pycommand.CommandBase and pycommand.run_and_exit.
• Code generator is included in the package itself instead of
  using an installed script (pycommand init)
• All templates are now included as well

Removed

• Pycommand init script (installed into /usr/local/bin)
• Templates directory
• GNU info docs and manpage from distribution (they can still be generated)
  • pycommand.3 (prev. installed into /share/man/man3)
  • pycommand.info

Syntactic sugar

Added

• Shortcut run_and_exit() for reading from sys.argv[1:] and exiting
  the interpreter via sys.exit(status)
• Package as wheel distribution to speed up installations
• Add man pycommand ability, i.e. install mandoc in /usr/share/man3/

Changed

• Add support for getting flags by attribute like self.flags.help.
  The default approach for normal dicts like self.flags['help']
  remains valid.

Template generation and better subcommands

Added

• Full example of a command with subcommands
• Create quick templates via pycommand script (pycommand init)
• Unit tests and automatic testing via Travis-CI
• Documentation man (.3) and info (.info) pages

Changed

• Specification of subcommands can be defined in CommandBase.command
  as a shortcut. (a978a05)
