Change cmd_*.so to use the Module object API

Create Module* objects for each command, and load them like modules.
This unifies the external API for modules.

Library directory is now deprecated: all modules are located in a
single module directory.

Header files for each command are no longer needed; remove.

This also fixes two potential segfaults in m_spanningtree.
