Add data for `DriveableMotorCycle.esp`.

As supplied by @Kelmych - thanks!

Closes loot/fallout3#72.
Add style check: `name`s should be '-quoted.

However, failure here won't fail the build, it's just supposed to add
some more information to the "build" log for editors to be able to
easier catch more things.
Add "headers" to the various parts of the testing.

For (hopefully) better overview in the testing report.
