Use the existing PluginDatabase to query for the plugins we can handle.

The original implemention of FrameLoaderClientBlackBerry::createPlugin
was a partial copy from another port.  In the Qt port there is some
workarounds for flash which is why this exists there.  Sadly the bits
that were copied made it so only flash worked, but as flash was the only
plugin on the system this issue was not noticed until QNX tried to get
jnext working.  Tracing it down to this bit of code rather then
correcting it they hardcoded the jnext into the same block as flash was.

The blackberry port isn't specifically suppose to only allow jnext and
flash, but was an accident due to the way this code was developed.
