Esperanto [eo]

[SejdenGrauk]

Creating this to coordinate efforts with other Esperanto speakers!

I'm currently going through all the keys to fix or improve the translations where needed, and then I'll add the missing keys and check if we can fix the pluralizer (reported on #138).

If anyone is open to help, you are more than welcome! Please let me know here and we can coordinate!

Current tasks:

• Full review (~40% done)
  EO: some translation improvements and fixes #622
  EO: improvements and fixes for some sections #636
• Add new keys
• Fix pluralizer (Pluralizers for zh-ch/zh-cn and eo aren't found #138)

Some more sections reviewed! It's open as a draft for a couple of days in case someone here wants to take a look before merging <3
