A new state is added to `Editor` and `commands::Context` structs.
This state is managed by leveraging a new struct `RegisterSelection`.
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`
