Uivonim Versions Save

Bunch of stuff I don't remember.

• Added --wsl argument for WSL support (see #99).
• Added --nvim argument for specifying path to Neovim binary (see #2).
• Bugfixes and other minor things.

Added Windows release.

Added app logo, and probably other things I'm forgetting.

Performance fix in visual mode.

Migrate from Hyperapp v1 to Inferno

Initial implementation of GUI elements for hover, signature help, references, and document/workspace symbols.

See the wiki for info on how to set up the new LSP features.

Main thing is dead key support (see #13 and #8), and probably small things like bugfixes I'm forgetting.
