This commit adds basic autocomplete in xml files. This includes autocompletion
for elements, components, props, attributes, and javascript expressions.
It also:
- Adds "Go To Definition" support for props and javascript expressions in xml
- Support for the following directives: t-att, t-model, t-tag, t-debug, t-log
- Fixes t-else syntax highlight to be non-dynamic as the attribute value
should be empty
