Move to SQLite 3080301

This new version of SQLite offers significant speed improvements in my testing. For example, the time it takes to issue "SELECT * FROM tvshowview" (the first time the TV Shows library is opened) with 345 TV shows on a non-overclocked Raspberry Pi changed as follows. Times are in seconds:

          Before          After
          Mean   StdDev   Mean   StdDev  Confidence  Change
    Time  4.211  0.129    3.521  0.140   100.0%      +19.6%
