EE Stock Charts V11 Update

This update:
- Adds High / Low day values to the Prices screen
- Adds an “Add Cycle Lines” option to the chart’s menu. This can help identify and foreshadow repeating highs and lows
- Shows nicer alignment of prices in chart’s price box.
- Shows a spinner progress dialog while accessing internet to load data
- Checks for active internet connection to avoid crashes

There are also minor fixes for handling:
- Going forward and backward in a list that includes only 1 symbol
- Less cluttered right-hand Price labels on Chart for high price stocks (e.g. Samsung). Also, a fix for Follow Through Day (FTD) and Breakout charts for high price stocks (over 999,999)
