Enhance runPython_bot

[aahnik]

Description

I propose the following enhancements to the bot:
( note: I am the author of this bot )

• Logs should contain time-stamps in the deployer's desired time-zone instead of server time.
• Uplift ban from exponentiation ** as the cause of bug found and can be handled.
• Hanging in case of certain long calculations can be prevented.
• Reduce bot's response time by preventing the repetition of execution.

  earlier when there was no output after executing the code via python -c code, the bot would run eval(code).

• add new command /e to run pythonic expressions.
• add new commands /help and /code
• remove the dependency on Makefile as it had only a few lines
• add more detailed docstrings
• make the readme instructions simpler to follow.
• host the code for this in an independent repo, to make deploying and updating code on server steps easier.

Here is a gif of the new behavior of the bot:

Type of issue

• Enhance existing script
