Add support and labels for UI Internationalization and Localization

[carloshm]

Initial pull request with:

• addition of labels for different languages (added new ui_lang parameter in config as lang from DarkSky does not support all potential languages to be included)
• instead of using localtime, added Babel to include localization in dates (potential additional review for other not included)
• Fix text positioning to include multi-language labels

TODO

• add changes to webconfig project to be able to edit language in ui_lang
• review all dates for intl
• review ltr, rtl scenarios
• add more languages resource files
• review potential actions to wrap text

@genebean I considered adding this as a minor version and fix for positioning

Hello @carloshm! Are you actively using the code from this PR? I ask because I saw some pushes this morning that brought it to my attention. Either way, I'll try and review this shortly. Sorry for the long delay... burnout kicked in and I had to walk away.

Yeah, I just did some changes for my local parents setup. Latest changes moved app to open-meteo and local changes. It may need some review to merge
