Enough has changed to bump the version. We're skipping 0.1.x because
previously the CLI would always report version as 0.1.0, and we'd like
to distinguish it in bug reports..

- The runtime/ directory is now properly detected on binary releases and
  on cargo run. ~/.config/helix/runtime can also be used.
- Registers can now be selected via " (for example "ay)
- Support for Nix files was added
- Movement is now fully tested and matches kakoune implementation
- A per-file LSP symbol picker was added to space+s
- Selection can be replaced with yanked text via R

- 1g now correctly goes to line 1
- ctrl-i now correctly jumps backwards in history
- A small memory leak was fixed, where we tried to reuse tree-sitter
  query cursors, but always allocated a new one
- Auto-formatting is now only on for certain languages
- The root directory is now provided in LSP initialization, fixing
  certain language servers (typescript)
- LSP failing to start no longer panics
- Elixir language queries were fixed
