Now that we have cli args, you can actually configure rofimoji easily.
This is quite nice :)

This is cool 😁

Issue: #9

The Unicode consortium publishes a list of official annotations for
emojis. We can use those to make them easier to find :)

Issue: #9

Hopefully, this will make diffs easier to read

It's getting slightly unorganized and large...

Now you cann pass arguments to rofi using the `--rofi-args` parameter.
Note that it must be string!

Issue: #19

Fix handling of --skin-tone

Fix readme typo

When nargs=1 is given to argparse, it creates a list with one item, which is why
the additional [0] was needed when reading the value.

However, default='ask' means that the default value was 'ask' rather than
['ask'], causing the skin tone to be set to 'a', resulting in:

  Traceback (most recent call last):
    File "/usr/bin/rofimoji", line 1905, in <module>
      emojis = compile_chosen_emojis(stdout.splitlines(), args.skin_tone[0])
    File "/usr/bin/rofimoji", line 1870, in compile_chosen_emojis
      emoji = select_skin_tone(emoji, skin_tone)
    File "/usr/bin/rofimoji", line 1756, in select_skin_tone
      return selected_emoji + fitzpatrick_modifiers_reversed[skin_tone]
  KeyError: 'a'

Instead, don't pass nargs to argparse at all - with the default nargs value, we
just get the value (or default) back, so we don't need the [0] anymore.

Fixes #16

While we're adding cli args, let's have one for skin tone so that you
don't have to choose the same one over and over again.

First, the classical typing, our companion since v1.0
Secondly, the new "Copy to clipbard, paste and then restore the
clipoard" to work around Firefox's problems. However, as `Ctrl+v` does
not work with a console (and thus Vim), I changed it to use
`Shift+Insert`. Unfortunately, this copies from both clipboard and
primary depending on the application. To work around this (yay,
recursive workarounds), we just spam both with our emoji and restore
them later. What could go wrong?

Also, we now allow choosing a method using cli args or different
keybindings (`Alt+p` for copypasting, `Alt+t` for typing).

Make emojis insertion work in Firefox and Telegram

Solves #7 (hopefully)

Remove emoji insert timeout

Fix note for multiselection

Because `rofimoji` is not yet synced to the Manjaro repo, but some might
still want to install it.

readme: Touch up formatting

readme: Package added to Arch Linux repos

Might as well mention only Arch as users of derivative distributions
should understand.

As @hashworks correctly points out, yaourt is deprecated. The current
solution should be future-proof ;)

Closes #8
