RLGWebD: rlgwebd.js annotate

annotate rlgwebd.js @ 17:d3e3d6b4016b

rlgwebd: switch to dgamelaunch's SQLite database. The quickrypt utility is replaced with sqlickrypt, which takes a username and password pair and checks them against the SQLite password database used by dgamelaunch. This will be more extensible to using rlgwebd to register, change passwords, etc.
