Feature: add bountysource to github

[abate]

Currently, numerous websites provide the opportunity to establish bounties for resolving issues, bugs, and feature requests.

This feature has the potential to attract fresh developers to Seamly and accelerate the development process, making it more agile and efficient.

Additionally, considering the number of non technical users/contributors of Seamly, there could be a significant number of individuals willing to contribute financially.

It is important to note that this approach should not replace the existing democratic feature request model but rather complement it.

https://bountysource.com/ ( and there is a also a github specific integration to add a button on the side bar).

what do you think ? For one I'll be happy to chip-in some money to see a feature implemented or a bug fixed.
