Performance improvements for navigation parsing widget

[Waqar144]

• Navigation parsing now runs concurrently, so that it doesn't block the UI.
• Navigation parsing widget only refreshes if there was some change in the document structure.
• Remove excess regexes as those don't seem necessary.

Coverage remained the same at 12.512% when pulling 2c219cc on Waqar144:nav-thread into adb099b on pbek:develop.

Awesome!

This PR seems to break the AppImage OBS build: https://build.opensuse.org/package/live_build_log/home:pbek:QOwnNotes/desktop/AppImage/x86_64

I hope note more build systems will break. 😬

It will break.
I think we need to do:

QT += concurrent

[pbek]

Nothing else broke and I don't understand why.

https://launchpad.net/~pbek/+archive/ubuntu/qownnotes/+packages went through too...

But TravisCI tests are failing!?
https://travis-ci.org/pbek/QOwnNotes/builds/633815466

QWARN  : TestNotes::testNoteDecryptionFail() [Botan Error]  Invalid CBC padding

   Loc: [testcases/app/test_notes.cpp(129)]

Did you make a test testNoteToMarkdownHtml that expects a byte-matching html. (I changed the CSS today). Isn't that test a bit too much?

[pbek]

I'll adapt everything.

Strange, AppImage is still broken. https://build.opensuse.org/package/live_build_log/home:pbek:QOwnNotes/desktop/AppImage/x86_64

How can they not have QtConcurrent?

Did 9a090f0 work?

[pbek]

Didn't make a new release yet with it. Don't bother, I'll take care of it. 😁

Works
