Make quterofi/manage_quickmarks to read/write directly from quterofi.toml instead of the standard quickmarks file

[cortsf]

By doing this quterofi/set_quickmarks could be deprecated and there would be no need to restart qb after updating quterofi's quickmarks in any way. Even manual updates (using a code editor) on quterofi.toml would need no action from inside qb for subsequent calls to quterofi userscripts to work as expected.

• Consideri making this optional, by calling quterofi/manage_quickmarks with a --use-toml-file flag. So users could choose which variant to use.
• Keep performance (for low end computers) in mind Moved to a new issue: Minimize number of quterofi.toml reads  #47
• Provide scripts to convert from/to standard quickmarks files
