Use structure types for table arguments / return values

[NullEnt1ty]

Some functions are using tables for arguments or return values. The table structure is often referenced in the description of the argument / return value. There should be an additional field with that structure reference if there is a reliable way of extracting that information from the description.

Entity:FireBullets( table bulletInfo, boolean suppressHostEvents = false )

table bulletInfo
The bullet data to be used. See the Structures/Bullet.
