Compendium entries grouping/sorting by their Type

[strusik01]

Is your feature request related to a problem? Please describe.
The Compendium entries, like spells or trappings, are listed in alphabetical order only. It's hard for my players to browse specific types of entires.

Describe the solution you'd like
It would be great to have all entries grouped by their type, then alphabetically.
For example trappings list could be grouped as Weapons, Armour, Tools etc., spells as Fire, Light etc., and Careers as Couriers, Warriors etc.

If sorting by Types, it would also be great to include sorting by subtypes as well. Example: Trappings sorted by types AND Weapons sorted by weapons groups.

Describe alternatives you've considered
Even better (though harder to implement I imagine) would be a proper "Sort by" function. Sorting by Type, Name (Alphabeting A-Z / Z-A) would be very comfortable.

Various Compendium categories could even have their specific sorting options, like for Spells - sorting by CN, or for Trappings - sorting by their price.
