Extend QueryCollector from PDOCollector

To inherit widget assets etc (without having to upgrade)

Don't use helpers, use $app

Loossen constraints

Revert to the old format style. This wil still work (but deprecated),
but prevents conflicts because of raveren/kint. Fixes barryvdh#109

Set fixed composer version

Fixes barryvdh#109

Always prepare bindings first

And check if string, before checking encoding.
This should convert datetime instances to strings always and before
checking the bindings. Fixes barryvdh#108

Updates for dataFormatter

And restrict to 1.9.x, for future updates.

Check bindings for binary data

Fixes barryvdh#107
Copied back from the Pdo collector

Set timeline to false by default

Just use config

Doesn't use any views/langs

Add some phpdocs
