This improves the current history search feature by adding substring
based history search similar to ZSH. In case the `UP` or `DOWN`
buttons are pressed after writing a few characters, the start string
up to the current cursor is used to search the history.
All other history features work exactly as they used to.

This improves the already existing preview functionality by also
checking for the input completion. In case there's only a single
completion, it will automatically be visible to the user in grey.
If colors are deactivated, it will be visible as comment.
This also changes some keys by automatically accepting the preview
by moving the cursor behind the current input end.

This improves the completion output by removing the nested special
handling. It never fully worked as expected and required a lot of
hacks to even keep it working halfway reliable. Our tests did not
cover syntax errors though and those can not be handled by this
implementation. Those break the layout and confuse the REPL.
Besides that the completion now also works in case the current line
has leading whitespace.
Also improve the error output in case the completion fails.

The implementation of _getDisplayPos, used to compute the cursor
position and to find out how many lines to clear up when re-rendering
the readline output, was counting each line (except the last one) from
the input as one row, even if they were wraping. This caused some
rendering issues when the 'prompt' have at least one wide line ending
with a newline char, duplicating the lines at the top of the prompt when
calling _refreshLine (ex: when the user hits backspace).
This patch fixes the issue by computing the real rows count for each new
line in the input string.
