Revert "remove dependency to vim_bridge"

This reverts commit c5d527d906cc0836c29d3733bde518929fda69eb.

I revert since I modified files in src and run build.py, but previous
modifications of the original author were made to rst_tables.vim directly so
my modifications removed unicode character count bug correction.
