Can't use `--no-i3` at the same time as `--show myconfig.config`

[GuySartorelli]

I'm running wayland, so I don't have i3. I intend to use this for macros that don't require i3 and I see this tool has a --no-i3 flag to assist with that.

When I try to run ./macropad.py --show myconfig.conf I get this error output:

Traceback (most recent call last):

    raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: 'i3'

When I try to run it with --no-i3 (i.e. ./macropad.py --no-i3 --show myconfig.conf) I get "Too many arguments." followed by usage instructions.

Possible solutions

1. Auto-detect if i3 is available - if not, don't try to use it (i.e. remove the need for a --no-i3 flag at all)
2. Don't try to use i3 when using the --show flag
3. Allow using both --no-i3 and --show at the same time
