WIP: add vue file basic support, alias path, fix #79 #53

[yoyo930021]

Description

1. Add .vue file basic support, refer to vetur for implementation. fix Support for vue files (variable suggestions, mixins etc.)  #66
2. Use TextEdit to fix Intellisense autocomplete issue in latest build #79, because lsp spec write this:

The `insertText` is subject to interpretation by the client side.
Some tools might not take the string literally. For example
VS Code when code complete is requested in this example `con<cursor position>`
and a completion item with an `insertText` of `console` is provided itwill only insert `sole`. Therefore it is recommended to use `textEdit` instead
since it avoids additional client side interpretation.

3. Add resolve alias path on config, and fix resolve error node_modules path. Implicit import finding wrong file #53

TODO

• add more test

Thanks for the contribution! I really appreciate it. 🎉

Can you divide this pull request into several by the number of issues being fixed? For example, I am now ready to accept a bug fix for #79, but not ready to accept a new option without investigation from my side.
