Add maintenance mode messages across the application (#1843)

Language Forge is now in maintenance mode. This PR adds appropriate messaging about maintenance mode and promotes FWLite as a viable alternative to LF.

Specific changes:

- Header now includes link to FWLite
- About menu includes link to FWLite and maintenance mode doc
- New project wizard includes message and discourages users from creating new projects
- Front page includes the maintenance mode message
