Improve localization

[Ascrod]

Most of the localization files are missing a property for "readerView.disabled", which displays in a tooltip on the Reader View button when it is grayed out. In English, the tooltip says "Reader View Unavailable". I've added some preliminary translations for several locales, but these are very rough and likely need to be proofread by native speakers.

Suggestions and pull requests for this are more than welcome!

Hi @Ascrod, I have submitted PR #30 for a few edits to the TL locale.

Thanks! There are a few features on the way that will require some further localization updates, and I was hoping to finish them before merging the PR in. I'll update this issue and the thread on the forum when those become available.

To follow up on my last comment, I have added a new feature for showing and hiding images. This includes two new strings in the properties file here.

With the addition of some new preferences, a new locale file has been added and, subsequently, needs to be translated.

If you have a Dutch locale I'll be more than happy to proof it in a few lost hours.
