Moved to objects

Moved most from main to file of the bot and lainbot object

Proposed usage for command '!YOURCMDNAME':
- create method with format YOURCMDNAME_command
- add line into help_command for your command
- if your command results in one-line response, return a str
- if your command results in multi-line response, return list of strings
- if your command needs to use another methods, put them in separate file, leave lainBot.py only for the commands

everything else should be handled automagically

This also allows the bot to reply on messages in channel and in query
