when an instance of MeekroDB is created, its default settings will be those of the static instance
functions generally shouldn't keep going after a nonsql error
%? no longer handles arrays and hashes for security purposes
those are moved into %l?, %ll?, %hc, %ha, %ho for different uses
few minor cleanups to last commit
escape and sanitize could be occasionally useful as public functions
additional test with %li0
oops
