New Features

:AstroReload command added which is an experimental live reloading feature. It may cause some instabilities in the editor after the reload, but any issues should go away with a restart. (Full announcement here: #862)
Use lspkind to unify LSP symbol icons across all plugins and the user interface (This adds plugins.lspkind configuration table as well to easily modify LSP symbol icons)
Add autocommand to automatically close AstroNvim if the last buffer that is not a sidebar is closed
Added visual mode LSP bindings <leader>la and <leader>lf for ranged code actions and ranged code formatting
For Neovide users: the provided default_theme colorscheme now sets the terminal colors appropriately to match the theme
