Create the user's config init file if lite user's config directory does
not exists.
No longer use the awkward package.searchers but instead add user's
config dir at the end of package path.
It basically works by setting the data directory to
$prefix/share/lite-xl
where $prefix is determined so that $prefix/bin corresponds to EXEDIR.
The packages 'user' and 'user.*' are loaded from the directory
'$HOME/.config/lite-xl'.
The problem was that when the editor had no events the cursor was not
blinking because the event loop was blocking on wait_event.
Now we no longer calls wait_event without a timeout if the windows has
the focus. When the window has the focus the timeout is set to 1 / fps
so that the cursor can blinks.
In addition we react to the "focus lost" event to ensure the documents
are redrawn without the cursor.
To avoid excessive memory usage when opening in a directory with too many files.
Introduce the config variable config.max_project_files to choose the limit.
The mechanism introduced avoid using excessive memory but it fails to
let user access all the files in the directory. A better implementation
should not impose any limits but read each subdirectory on-demand, only
as they are expanded in the tree-view.
As the window isn't created until the first frame is drawn this is required to
assure the window is ever shown without relying on the assumption that some
other part of the program would have set this to true
Filenames that match either the single pattern provided by
`config.ignore_files`, or any pattern in a table of patterns, will be ignored
when lite is filling the `core.project_files` table
