More improvements:

- Include "Volume (24hr)" in homepage summary
- Include block output volume in blocks list (0.17.0+)
- Show "%Full" in blocks lists (with fullness icon) instead of weight with progress bar
- Hide "Date" column on homepage blocks list (Age+TTM) is plenty for the recent blocks)
- Fix to pull UTXO set after RPC connection is established
- Fix for abbreviating "month" to "mo" instead of "m" which can be confused with minutes
- Tweak width of data columns on 1200 screens to avoid some wrapping of title labels
- More consistently "smallify" display of units
- Armor on block-content template for missing blockstats values (identified issue by looking at genesis block, added manual data for that block since RPC returns error, but armor is still probably valuable)
- Tweaks to timestamps "time ago" displays in several places trying to make more consistent and user friendly
- Explicit acknowledgement of "nonstandard" output type
