Random Lineage and Class Table

Have added this to the starter set and the Adventurers Guide.

The purpose is twofold; firstly when using quick builds to avoid player analysis paralysis on these two choices.

Secondly and optionally to ensure balance between lineages and class numbers for teh campaign. To avoid too many elves etc. as they are supposed to be uncommon.

Finally made a few Barbarian changaes including giving extra damage to mighty charge.
