Facilitate error reporting from within the app

[TbLtzk]

A new button (let's say in the about-tab) for reporting errors:

• automatically retrieve as much device information as possible (manufacturer, model, android version, screen resolution, ...)
• retrieve the apk version (should somehow be the value from config.xml)
• other helpful things like date and time, connectivity etc, suggest a category
• checkbox if the functionality worked correctly in a previous version
• Explain to the user, that all information is used exclusively for analyzing the error, nothing else
• Transmit the information (e.g. mailto [email protected])
• nice to have: display the apk version within the app
