This:
- Changes version number everywhere I could find it.
- Reworks get_version() to dispense with stable / dev division.
- Rewrites CONTRIBUTING.md to describe a new release workflow.
The development/release workflow stuff could use some thought. It's
clunky at best. There's sort of an inherent tension between semver-style
version numbers and the rolling release thing - maybe we should just use
commit hash or something date-based?
Still, it's a start.
Refaction:
- Add g:vimwiki_syntax_list to set syntaxlocal variables
- Delete: syntax/vimwiki_markdown.vim and friends
- Change: vimwiki_syntax_variables -> vimwiki_syntaxlocal_vars for consistency
- Include: some doc in design notes
