Show Filenames in Multishell Title

[JakobDev]

With this PR, you can directly see, which File is opened is which tab, if you have multiple files open.

I wonder if it'd be worth limiting file names to 20 characters or something? Maybe something like:

local name = fs.getName( path )
if #name > 20 then name = name:sub(1, 17) .. "..." end
if multishell and settings.get( "paint.multishell_title" ) == true then
  multishell.setTitle( multishell.getCurrent(), "paint (" .. name .. ")" )
end

This way really long file names won't fill the tab bar, but most file names will still display fine.

Max length as a settings option?

@lupus590 Whiyh is a good name for this settings? Maybe multishell.max_filename? What do you think?

[Lupus590]

I would suggest multishell.tabTitleMaxLength (or is underscore the established convention?)
