DH2 Fixed

Liked my other script from DH1? Here is my response to DH2.

This userscript adds some features and fixes some issues to improve your game experience.

Adds completely new chat with pm tabs, clickable links, clickable usernames (to send a pm) and intelligent scrolling
Adds smelting and tree growing timer and changes other timers to look like the ones in DHQoL for DH1
Adds calculated times until an event (like collecting sand) happened at least once with different probabilities (1%, 10%, 20%, 50%, 80%, 90%, 99%) - these information are available on hover in shovel popup and fishing rod popup (for all types of fish - can be seen here: http://imgur.com/a/ElG0g)
Adds information (instead of the text "1") for some bound items: capacity for furnace, oil cap for oil storage, tier level for tools, oil production for oil items and current state for boat/canoe
Adds requirement tooltips for recipes
Hides furnace, oil storage and oven recipes if they aren't better than the current level
Hides recipes of maxed machines or owned items which are not stackable
Detects spamming in chat and hides spam messages (may be obsolete since the server has some spam detection)
Fixes updating the brewing and cooking recipes

Changelog

add showing the remaining time of maple trees
improve boat caption to show there is only one boat at a time allowed
fix setting tooltip of lime leaf seed with DH2QoL enabled
change slightly delayed setting of autoscroll when using intelligent scrolling
huge performance boost for chat (especially with more than 900 messages - scrolling inconsistencies are fixed)
add tooltip for timestamps in chat

add close button for pm tabs (thanks /u/Spino-Prime)
add tooltips for requirements of cooking recipes
add fix for hero being clickable during combat
fix some issues when used with DH2QoL (tree timers, oil consumption/production)
fix always showing combat start timer
lots of improvements/fixes for chat:
- remove vulnerability for zalgo text
- fully restore copyability of the chat messages ("Server Message"s are select-/copyable again)
- add chunk system for chat to improve responsiveness of the whole page with a long chat (activates at more than 900 messages): Groups chat messages in chunks (technically divs) to hide non-visible chunks and un-hide them on scrolling through the chat. This introduces important performance reduction (e.g. for reduced power consumption). Though it is so far only tested in Google Chrome. Please inform me about occurring problems via reddit: /u/TheZorbing.

add fix for updating cooking recipes
improve chat further:
- make counter for new chat messages more prominent
- move tag to username to be more space efficient
- reduce space used in pm tabs
- fix chat to produce complete and copyable text (includes time and user level)

add fix for wobbling elements in wood cutting tab when hovering over one chopping area
hide furnace and oil storage recipes if they aren't better than the current level
