Garrett D'Amore 8f08469772 fixes #167 Break up the database 
This completely restructures the database of terminal types, putting
each terminal in its own file.  We also compress the database files,
and use infocmp instead of trying to use the C level API.

The mkdatabase script will rebuild the entire database from the terminfo
files on the system.  Individual entries can also be built by simply running
the mkinfo program with the terminal type.

// -gzip specifies output should be compressed (json only)
