Azazel Purchasables - Elixiers (#2156)

* Implementing #2110

* Added summon KV and extra abilities

Assumed 300 MS for farmer and 1.0 turn rate for all summons.

* Added azazel summon item entries and basic functionality

* Finished implementing #2111

- Used "funny" names for the summons, just change them if you don't like them or think they're not clear enough.
- Summon stats are tied to their actual stat block in npc_units_custom; the values in the item just change tooltips.
- The Farmer's cleave stats are tied to the ability's KV, not the item's; again, the item's KVs just change tooltips.

If the whole KV/tooltip thing is a bother, it can be changed, but I thought it was outside the scope of the issue, since the current behavior is easier to implement and consistent with (almost) every vanilla summon ability in the game.

* travis

* missing tooltip for modifier "dota_tooltip_modifier_azazel_summon_farmer_innate"
 - it's a hidden modifier that needs no tooltip.
* item/ability ID conflicts
 - fixed
* "cost is set correctly in kv for item_elixier_sustain_4"
 - I assume this means incorrectly. The items all cost 100g (recipe) + their core's cost (1500/2500/3500/4500) so I don't see the error here, but i set everything to 100 anyway, assuming cores have no real value.
* "[item] has reverse compatible upgrade [core x]"
 - If I understood correctly, this is intended.
* blah blah whitespace
 - fixed
* blah unused variable
 - fixed

Also made the items temporarily purchasable in the regular shop.

* seems like travis' "next free ID" is a fat old lie

fixed conflicting item/ability IDs

* test

test

* Fix Travis
