Evince Backport: Allow adding Highlight annotations from text selection

[m8]

It is really practical to be able to add it as highlight after selecting the text. Constantly, it's hard to add from the menu. I backported it from Evince. Might be a good PR if you can test it.

As this is a natural, intuitive way to add text markup
annotations to a document.

The "Highlight Selected Text" action
in the context menu
will show if there is a selection. When
the selection spreads over several pages,
one annotation per page will be added accordingly
to fulfill the user expectation of all selected text
to be annotated.

I noticed that there are some bugs in the annotation locations when it is saved. I am working on it.

just mentioning that, apart from context menu facility, directly pressing ctrl H and alt H highlights too, in evince and deepin reader respectively, after selecting text.

@sidmint yes it will be nice, there was a small bug about saving locations of annotations. after fix ıt can be implemented very easily.

Hi, this feature is still not there, right?

[sidmint]

#547 similar request.
This basic feature is still missing and manual option of adding highlight/annotate is very unintuitive to find.
Evince got this long ago, new epub reader to be launched which is mentioned in blog has it from day one.
