Remove todo list (now using gitlab issues instead)

todo.txt

-first:
-- split rocket and exhaust into separate elements
-- add camera container around stars + rocket that handles rotation (points
-  stars and rocket in same direction, makes animations easier by only requiring
-  left/right/width properties to be animated)
-- animate exhaust flames
-- create slope poller to determine rocket flying angle (either calculate from
-  tickers or pull from some website, e.g. bitcoinwisdom, in the latter case
-  also try to get the tickers from there)
-- fix ticker polling
-- properly scale dashboard
-- make it work on mobile (good element dimensions + smooth animations)
-- add more states for different slope levels: divide the flying angle in
-  segments and assign a state to each segments, with transition animations
-  between each state
-
-later:
-- move/scale moon depending on market
-- replace images with final ones of lower resolution (maybe use css background
-  instead of img tags)
-- bitcoin donation address + QR code
-- add easter eggs
-- add sound?
