cursor handling with utf8 support
the code relative to the cursors movements now respects the width of the characters (zero, one or two cells).
starting to implement TOFU
popuplate an hash table with the certs and keep it in memory. Later, store the table in ~/.telescope/known_hosts and re-read back during startup.
added fs process
it's the only one that has file system access. For now it serves about:new (from memory) and about:bookmarks (from ~/.telescope/bookmarks.gmi if found)
