VimTeX 2.9

I'm happy to announce another release of VimTeX. There is mostly minor improvements since v2.8. The main improvements are:

• Added ts$ command to toggle inline and displayed math
• Improved the cs$ command
• Simplified the viewer interface (this should be mostly invisible to users)
• Several improvements to syntax highlight

Although, of course, even minor improvements and fixes are useful to ensure long-term stability and life time.

    • We now never allow latexmk to start the viewer "implicitly"
    • Breaking: Removed option g:vimtex_view_general_options_latexmk
