simplification and major rework

* updated gitignore file
* partly reworked servercontact implementation
* complete rework of uptime, version
* part rework of xep requests
+ added more comments to xep requests
+ added opt_arg to version, xep and contact
* complete rework of validate function
* updated HandleError function
* part rework of StaticStrings function
+ implemented data dictionary to hold all data in main bot
+ added message_ids
* complete rework of queue building and deduplication
