changelog, documentation, and distrib updates for ergo 2.7

fix #1669

Sort snomasks for display rather than displaying them in hash order

Update status badges in readme for project rename

fix znc.in/playback for individual DM targets

This is a regression introduced in 0d05ab4ff4; playback for an individual
DM target would play all DMs.

Update run.sh to use newly renamed ergo binaries

Improved Spanish translations

Notable changes:
* Use of inclusive pronouns and words (think they/them but on a language
  that relies on gender for almost every word). Keep in mind this might
  cause some flame from conservative folks.
* Corrected many computer-generated translations (one of them translated
  "resume" to resumé)

fix #1661

If the relay bot and the owner share an IP, legacy bots that identify users
by user@host could misinterpret relayed lines as coming from the bot owner.
Try to avoid this by using the bot's account cloak where applicable.

fix #1647

Send a full NUH with RELAYMSG.

Also fix client-only tags with RELAYMSG.

Add documentation for +f channel mode.
