v1.15.1: Make --quit-if-one-screen instant

Before this change, there was a very obvious flashing of pager contents
when running with `--quit-if-one-screen`, even when input handling was
fast.

With this release, moar will exit as soon as file reading and
highlighting is done, providing a much nicer experience in the common
case.

v1.15.0: Support not paging short inputs

This release adds a --quit-if-one-screen command line flag. Given this
flag and some input that fits on screen, moar will exit immediately and
print the input to stdout.

v1.14.0: Add support for terminal hyperlinks

As described here:
https://gist.github.com/egmontkob/eb114294efbcd5adb1944c9f3cb5feda

Fixes #131 and #133.

v1.13.0: Configurable side scroll amount

Using the new `--shift` command line flag, or by holding down ALT while
pressing the left / right arrow keys to move one column at a time.

v1.12.0: Display Private Use Unicode characters

Before this release, we rendered those as highlighted question marks.

With this release, we just send them to the screen for displaying.

The reason for this change is that Font Awesome uses Private
Use Unicode characters for symbols, this one for example:
https://fontawesome.com/v4/icon/battery-empty

Also, with this release, you can press 'q' to exit Go-to-line mode.

v1.11.4

Accept pasted text in the search field

v1.11.3: Support LESS_TERMCAP_so environment variable

For backwards compatibility with less. The variable's value will be used
for coloring search hits and the bottom status bar.

Fixes #114.

v1.11.2: Add more highlighting styles

By bumping Chroma to a much newer version.

Relates to #112.

v1.11.1: Add --follow command line parameter

For automatically following piped input, just like "tail -f" (part
of #108).

Also add ^p and ^n for scrolling up / down (part of #107).

v1.11.0: Added support for following input updates

Just like `tail -f`!
