v0.9.0 – forms, menu controls and the menu designer

• Menu designer in the browser (https://flyingfinger1.github.io/Glyphwork/designer.html, next
  to the skin editor): place and resize elements with the mouse, edit their options, variables,
  forms and templates in side panels, try the menu out (actions, controls, forms work on preview
  variables) and download the .yml file. Load your own Minecraft client jar (read only in the
  browser) for real item icons and the real font; resource packs add their textures and items.
  Guide in docs/menu-designer.md.
• Forms: several native input fields at once (text, multi-line text, slider, checkbox,
  choice) in a dialog of their own with OK / Cancel; afterwards the menu is shown again. In YAML a
  menu lists them under forms: and opens one with the action form: name; every field belongs to
  a menu variable (starts with its value, OK writes it back), then the form's actions run. API:
  Click.form(Form, values -> ...); values are checked (length, range, step, known options).
  New example example-forms.yml; the example trader picks its amount with a slider.
• Slider, checkbox and choice in the menu: new elements drawn from the skin (slider,
  checkbox, choice in YAML with var:; Slider, Checkbox, Choice in the API). A click on a
  slider's track moves the knob there (hovering shows the value first), a checkbox toggles, a choice
  button steps back (left half) or forward (right half). The variable is set, the element's
  actions run and the menu redraws. The plain dialog offers them as buttons (one step down/up,
  toggle, next option). example-forms.yml shows them next to a form.
• Counts on icons: count: 64 (YAML, also for list and grid items, placeholders allowed) and
  Icon.count(...), Grid.count(...), ListView.count(...) write a stack size at the bottom right
  of the icon, white with a shadow like in the inventory; 1 and empty show nothing. The plain
  dialog writes it after the name ("Diamond ×64"). The example trader shows its pack sizes.
• Auto-refresh: refresh: 5 in a menu (or Scene.Builder.refresh(Duration)) redraws the open
  menu every few seconds, so placeholders and dynamic lists stay current. Clicks on the previous
  drawing still work; it stops when the player closes the menu (also with ESC), opens another one or
  an inventory. example-players.yml refreshes every 5 seconds and shows the players per world as
  counts.
• Text shadows like in vanilla: the text of buttons, lists, grid cells and the page arrows now
  has a drop shadow (before, all text was flat). Grayed-out buttons stay flat, and so do labels,
  like inventory titles; shadow: true (YAML) or Label.shadow(true) turns it on for a label.
  Arrows of a page button that cannot be used are gray now.
• English examples: the example menus exist in English (example*.yml) and German
  (beispiel*.yml); on first start the set of the server's language is exported (language, or
  fallback-language when it is auto, default English). The demo (/glyphwork test) speaks the
  player's language (keys demo.* in the language files), and the example plugin is in English
  (/trader, /haendler still works).
• Skins renamed: the built-in skins are now dark and parchment (were dunkel and
  pergament).
• List frames and the menu background are rounded up to whole tiles: rows of a list whose
  height is no multiple of 8 (2 rows of 18 px) stuck out of the frame, and content near the bottom
  of a menu with such a height sat on or past the edge. Other frames still round down.
• New placeholder %time%: the server clock (HH:MM:SS).
• Closing a menu with its exit button or ESC now ends the player's session right away (before, it
  stayed until the next menu).

Upgrading: the built-in skins dunkel/pergament are now dark/parchment; if your config says theme: dunkel, change it to theme: dark (the old exported folder keeps working until you delete it).
