This commit introduces pokememes information storage in source code (because they're rarely changed and I always update them manually).
All information about pokememes updated after nerf of 25 April. Also, added buttons to /pokedeks command for changing pages (there are 21 pages already!), and limited one page to 35 pokememes.
So, now we can handle 10th grade pokememes (and any two-digit grade pokememes in future).
Also, /best and /advice commands for 9th-level players respect new pokememes.
Recent game update changed pokememes view in pokedeks, so we need to
reflect it by updating parser.
Introducing DataCache - a silver bullet for eliminating lags linked to
database queries. Less queries, more in RAM, faster work. Needs testing
in production environment.
