• Added the changelog page.
• Lua: add trade:legs() which returns an iterator of Legs
• UI: add 'Download NAV' button to Run Output which downloads datetime,NAV as CSV.
• Remove the "Share this script:" box since it's simple to share the lua code. The "Share" functionality which shares the result of the backtests remains.

• Updated backtester handling of missing data.

• Add 30-minute tick data. Available with sim_params.archive = "SPX-30". From there, it's possible to do sim_params.tick_time = "14:00" and if you want to tick every 30 minutes: sim_params.tick_interval = "30-minute". If you do so. Be sure to add a guard so you don't enter a trade every 30 minutes.
