Subject: [PATCH] Cosmetic: fix logging

Output stake_amount as it is defined in the config (it may by int) instead of float. In order to avoid unnecessary questions where and why it was converted to float and changed in the last digit while it should be integer for the exchange...

Other small cosmetic improvements to logging in freqtradebot.py
