Make title shortening optional

[alvarezfmb]

I found the default shortening frustrating, titles on websites are pretty much always not shortened. I understand the requirement since you never know which kind of feed the users would be adding, but I'd like that feature to be optional. I've pushed the changes to a branch on a fork. Default behavior is maintained, a new toggle is added. Pasting some screenshoots of how this looks, Techmeme is a great example of information dense titles that were usually shortened.

It's been previously discussed here, but the issue was closed, but it's not clear if it was a non-negotiable from the dev or just that they didn't want to make the app have a "how many max lines" picker (I agree with that, but a boolean option is simpler).

Here's the fork: https://github.com/alvarezfmb/capyreader/tree/fa/full-titles

Hey @alvarezfmb thanks for commenting on this. I didn't want to add a picker for the reason you mentioned - it's just a lot of overhead to consider from a user perspective. I do like the framing of "Shorten titles."

Please feel free to open a PR with that branch. I have a few suggestions, but overall the code structure looks good!
