Add option to change the language of the weekdays or to the add event menu and more

I'd love to be able to localize this plugin to my dates, language and more, like the rest of Obsidian

This is related to #72. Localization is a notoriously hard problem for web apps, and since this is a project in my spare time, I'm not sure if I can take it on. Especially as someone who only speaks 1.5 languages. I will tag these issues as "help wanted", in case others can help contribute on this front.

hi davish,
just found this settings in fullcalender API: https://fullcalendar.io/docs/locale
If i understand @Trigant right, that should meet his requirements.

• For me as native german speaker it is ok to have an additional plugin setting to initialize the fullcalendar in my language.

Here is the demo language switcher: https://fullcalendar.io/docs/locale-demo
