- move the alias syntax and usage docs from dfhack-config/quickfort/aliases.txt to a proper guide written in RST. Add examples and more details.
- move the alias library docs from data/quickfort/aliases-common.txt to the new guide
- reorder aliases in aliases-common to match the order in the docs

- do an editorial pass of the quickfort user guide
  - change name to "Quickfort Blueprint Guide", but only in the text, not the filename, so we don't change the URL

  - changed "grid" tables into "simple" tables where possible
  - used ':kbd:' markers whenever we refer to a single character
  - turned Meta blueprints and Notes blueprints sections into subsections of a new "Other blueprint modes" section, in preparation for a few new modes coming in -r5.
