Export / share option

[BuZZ-dEE]

Add export / share option for expenses
For example:

• as (mobile friendly) PDF function
• as .ods function (https://www.libreoffice.org/discover/calc/)
• or other formats

@BuZZ-dEE Thanks for submitting the issue. I'll think about export options in the future and will investigate how this could look like, however it is not something I'll focus on soonish. But if someone else would like to take this I'm totally open to it.
I'll close #322 and merge it with this one to have a general export feature request.
Feel free to suggest more details on how you would like to see this.
