Don't truncate or round data in tables

[keastrid]

• [ ] Change how manual trimming in MP rebuilds the table from the TextPanel, truncating and rounding all values
• [ ] Some values added to the table by MA and AP are rounded when they are added
• [x] Save full data to file, not the TextPanel contents
• [x] Keep display with rounding/truncation the same (the above changes are only for the internal table representation)
