Progress on v0.7

[altermo]

I have been working on the next version for quite a while now, so here is a progress update:

• Ultimate configuration system:
  • Pair config is merged with global config, meaning that you can do pair-specific configuration
    • Almost all tables support a merge flag (default: true) to merge with the global config
      • This solves the problem where you want to over-ride (instead of extend) a list value from the default config
  • There are special short name options that expand to longer ones (like ft=... becomes filetype={ft=...})
  • Examples:
    • {{'(',')',ft={'c'}} becomes {{'(',')',filetype={ft={'c'}}}}
    • {filetype={ft={'lua'}},{'(',')',ft={'rust'}} becomes {{'(',')',filetype={ft={'lua','rust'}}}}
    • {filetype={ft={'cpp'}},{'(',')',ft={merge=false,'markdown'}} becomes {{'(',')',filetype={ft={'markdown'}}}}
• TSNode/Injected lang detection now uses treesitter queries instead of traveling the tree
• Can now have multiple instances running at the same time
• Many extensions became filters
• True utf-8 support (removed the utf-8 extension hack)
• Better tests (using RPC)
• A much better way to manage mappings (and auto-commands): the hook system
  • Only the expr-map is implemented for now

Some breaking changes:

• space mapping is no longer enabled by default
• Many changes in configuration
  • Some extensions are now filters
    • Ex {extension={alpha=...}} becomes {filter={alpha=...}}
  • Some extension/filter options are now removed (as they are no longer needed)
    • Ex alpha.all is removed as start/end pair-specific configuration is now possible
  • map/cmap becomes map_modes={'i','c'}
• Most extensions are now filters (requires changing the configuration)
