Upgraded to compojure-api 0.14.0.
Added path-params to endpoints with integer IDs.

Removed param/string-to-int call in org.ocremix.api.entities/get-entity-info since compojure-api automatically converts these path-params to Longs.
Refactored entities/remix and entities/system to use entities/get-entity-info since it no longer requires an integer ID.
