Thanks to thorsten!

This is required to customize it via stylesheet.

Furthermore, add documentation on how to configure vim.

This introduces the setting single_instance_per_file and
the command line flag --single-instance.

This is better for shell completion. It is now called
synctex-katarakt-vim.py

Thanks to Sergey Romanov.

Katarakt now exposes a dbus-API that allows TeX-editors to synchronize
the positions in source code and pdf via synctex.

TODO: The API allows to specify positions in the PDF as (page,x,y)
triple, but the x,y coordinates are currently ignored or set to 0,
respectively. We need more katarakt-internal API for this to be
implementable.

The file relied on a tabwidth of 4

Thanks to Thorsten for finding a solution
