[Advanced Paste] Add advanced text formatting

Description of the new feature / enhancement

Make AdvancedPaste more versatile by giving more text editing shortcuts, such as convert to single line (to get rid of linebreaks when copy pasting from a pdf), capitalize (correctly capitalize a sentence / convert to upper/lowercase), etc.

Scenario when this would be used?

This feature could be used during essay writing. When copying information from a pdf over to for example a google doc, it would be helpful to be able to select the text and paste it as a single line.
