Import Bookmarks/Notes

[meichthys]

Is your feature request related to a problem? Please describe.
Complementary to #189 which would implement Bookmark/Note exports

Describe the solution you'd like
Being able to import notes would make it possible (or easier) to migrate from other Bible study apps.

Describe alternatives you've considered
Currently the only method to migrate notes from another Bible Study software is to manually copy/paste every single note.

Additional context
Software like OliveTree provide export formats (csv/xml) With minimal excel or scripting we could reformat the notes into a format that AndBible would accept. Perhaps some folks could even provide simple scripts to make this even easier.

Sounds doable. As #189 also few hours of work probably.
