Allow bot to use better balls if it fails to capture repeatedly

[shoelsch]

If capture keeps failing with pokeball, upgrade ball.

[22:57:16] Something rustles nearby!
[22:57:16] A wild Kabuto appeared! [CP 765] [Potential 0.51] [A/D/S 15/2/6]
[22:57:19] Catch rate of 23.05 with Pokeball is low. Throwing Razz Berry (have 9)
[22:57:19] Threw a Razz Berry! Catch rate with Pokeball is now: 23.05
[22:57:19] Used Pokeball, with chance 34.57 (24 left)
[22:57:20] Kabuto capture failed.. trying again!
[22:57:21] Catch rate of 34.57 with Pokeball is low. Throwing Razz Berry (have 8)
[22:57:22] Threw a Razz Berry! Catch rate with Pokeball is now: 34.57
[22:57:22] Used Pokeball, with chance 51.86 (23 left)

[22:57:36] Kabuto vanished!

First, let me know if there's some configuration parameter I'm missing.

I think it's ridiculous in the case above that a pokeball was used 7 times in a row and failed 7 times in a row before the pokemon in question vanishes. By my calculation, the event above occurs in ~1% of cases (if we assume that the chance % is accurate): (1-0.5186)^7. Still, I would expect the probability of a pokemon vanishing to increase over the duration of an encounter and for the bot to be intelligent enough to expedite the capture in this scenario.

Again, tell me there's a config option for this if there is: give me the ability to specify my default ball preference for pokemon (e.g., I want to use an ultraball first and foremost if I encounter a Kabuto); allow the bot to switch to a better ball if its failure rate seems to contradict the catch rate.

in config.json you specify your wanted pokemons at "vips" value as below. The bot always uses ultraball to catch them.

    "vips" : {
         "Kabuto" : {}
    }

@kesfaw thank you. closing the issue.
