Ability to Pause bots#46

We need a way to pause bots to stop all activity immediately. This instantly stops bots from executing entries and take profits. Pausing bots prevents them from draining money out of the account when sharp drops occur. This does not replace deactivating of bots, but instead provide a different functionality.

For example:

1. User expects a sharp drop, does not want to buy/sell at current prices, and/or does not have enough money.
2. User pauses the bots, which stops all buy/sell activity.
3. After a while, user resumes the bot, with one of the below outcomes:

A) If a drop occurred, execute first missed entry (buy at lower price), and re-adjust remaining entries.
B) If a rise occurred, execute take profit that was missed (sell with more profit).
C) If no major change occurred to price, resume without any changes.
