Add :earlier and :later commands that can be used to navigate the full edit history. (#194) 
* Disable deleting from an empty buffer which can cause a crash.

* Improve on the fix for deleting from the end of the buffer.

* Clean up leftover log.

* Avoid theoretical underflow.

* Implement :before which accepts a time interval and moves the editor to
the closest history state to the commit of the current time minus that
interval. Current time is now by default, or the commit time if :before
has just been used.

* Add :earlier an :later commands that can move through
the edit history and retrieve changes hidded by undoing
and commiting new changes. The commands accept a number
of steps or a time period relative to the currrent change.

* Fix clippy lint error.

* Remove the dependency on parse_duration, add a custom parser instead.

* Fix clippy errors.

* Make helix_core::history a public module.

* Use the helper for getting the current document and view.

* Handled some PR comments.

* Fix the logic in :later n.

Co-authored-by: Ivan Tham <pickfire@riseup.net>

* Add an alias for :earlier.

Co-authored-by: Ivan Tham <pickfire@riseup.net>

* Add an alias for later.

Co-authored-by: Ivan Tham <pickfire@riseup.net>

* Run cargo fmt.

* Add some tests for earlier and later.

* Add more tests and restore the fix for later that diappeared somehow.

* Use ? instead of a match on an option.

Co-authored-by: Ivan Tham <pickfire@riseup.net>

* Rename to UndoKind.

* Remove the leftover match.

* Handle a bunch of review comments.

* More systemd.time compliant time units and additional description for the new commands.

* A more concise rewrite of the time span parser using ideas from PR discussion.

* Replace a match with map_err().

e2d780f993 fix: 2 panics while setting style + off by 1 
The panics would occur because set_style 
would draw outside of the the surface. 
Both occured using `find_prev` or `till_prev`
In my case the first panic! would appear
in a terminal with around 80 columns 
in helix/README.md going to the end of the file
with `geglf(`
the second with `geglfX`
The off by one fix ensures that `find_nth_prev` 
starts at the first character to the left

8a29086c1a Fix panic when moving over unicode punctuation 
`is_ascii_punctuation` will only work for ASCII punctuations, and when
we have unicode punctuation (or other) we jump into the `unreachable`.
This patch fallback into categorizing everything in this branch as
`Unknown`.

Fixes https://github.com/helix-editor/helix/issues/123

https://github.com/helix-editor/helix/pull/135: add better support for
unicode categories.

Bevore this PR `commands::find_prev_char` and `commands::till_prev_char` were triggerable through keys 
but `seach::find_nth_next()` was hardcoded in `_find_char`. 
The passed `fn` was nerver used. With this PR the passed `fn` is used.
The change in search.rs resolves an off by one error in the behivor of `find_nth_prev`

4a9d1163e0 Hacky way to specify indent scopes per language via toml configs. 
Can't do it via a scm query nicely because it returns an iterator over

Can't extract the pattern data from a parsed query either.

Oh well, toml files for now.
