$bootstrap is never defined in jqp.admin.inc

the variable bootstrap is put into the system table twice in this module, but is never defined. Most likely the schema should be cached, so $bootstrap should just be defined as false.

This was spawned by this error message I recieved when updating my site:
Notice: Undefined variable: bootstrap in jqp_rebuild_cache() (line 588 of /sites/all/modules/jqp/jqp.admin.inc).

To solve add to line 465

$bootstrap = FALSE;
