vanThos Utility

# vanThosUtility 1.0.19

## Fixed
- "Copy chat" opened an empty window: the copy box now has no length limit (a limited box refuses a long text as a whole, and the restored chat history makes the text long right away).
- The copy text is cleaned of escape codes the copy box cannot show (named colours, Battle.net names, grammar and line-break codes, stray pipes) and cut to its newest 60,000 characters.
- If the box still cannot show the text, a chat message says so instead of leaving the window empty.

# vanThosUtility 1.0.18

## Fixed
- Error "HealthBar.lua: attempt to compare local 'value' (a secret number value, while execution tainted by 'vanThosUtility')" about once per second with quest nameplates on: unit tooltips are now read as tooltip data instead of being drawn into a hidden tooltip frame with a health bar. Clients without tooltip data use a scan frame without any bar.

# vanThosUtility 1.0.17

## Fixed
- Chat copy after a reload: lines put back by the chat history are now part of the copy text again, in front of the new session's lines.
- A failure while storing a chat line can no longer affect the chat window itself.

## Added
- Font previews: a sample of the chosen damage number font and size, and a sample of the health/mana text in the chosen format and size, right in the options. A font file the client cannot load is shown as such.
