Track cligen changes

Necessary since this depends on cligen#head and some backwards incompatible changes were necessary to the alias system.

Icons, -X./., & auto-configure

Add new behavior to not honor .lc files while recursing unless -X arg ends with either "//" or "/.". In the former parents are searched, the latter not. Note that due to structure of the recursion if a top-level entry point has a .lc in "/." mode then those config mods are inherited through its recursion.

Add vector of "icons" (any utf8 strings really) capability.

Use new self-configuring cligen/[statx, magic]

Require cligen#head

This should avoid having to sync with cligen for changes in cligen/abbrev & friends.

Sync version with cligen

v0.4

Update for version management.

Use new cligen/abbrev

Best to release to keep in sync with screenshots in README.md
