Relevant commit, though I don't recommend trying to review it (101 files :) https://github.com/x-tools/xtools-rebirth/commit/fcf66fab76752b49079ca2408704d0a820d74bfe

No real changes here other than to the i18n directory, and updating everything to use the new message keys.

I'll list the squashed commit messages here:

• Underscores to dashes
• More human-readable message keys
• anonedits -> ip-edits
• authors -> num-authors (unused)
• actions-admin -> admin-actions
• Capitalization (English)
• Remove some duplicates, sensible renames
• More sensible renames, rm duplicates
• 'years' and 'weeks' to 'num-years', 'num-weeks', other fixes
• total-edits -> total-revisions, total -> total-edits
• user-table -> top-editors
• Update all tools to use new message keys
• page -> page-title
• No longer need 'select-language'
• rm time-ago, past-time, or
• Importing translation-credits, help-translate, user, hashtag-credits, history from Pageviews Analysis

I still want to import more messages from other projects, to save translator's time. I'll do that with a different commit/PR, just wanted to get this one merged because it's holding back others' work.

This commit adds qqq documentation, imports more messages from other tools, among other various i18n fixes: https://github.com/x-tools/xtools-rebirth/commit/54bb4b45c8eba8c1b1b7d32ba2221c2479dfb999
