Simple rate of return comparison

This simple indicator compares RoR for up to eleven assets over a period described by the "Offset" input variable.

RoR type may be:

• Classical logarytmic RoR: log((Po - Pn)/Po).
  
• Percent growth: (Po - Pn)/Po.
  
• Fiat evaluaton based on "Budget" input roperty: $ * (Po - Pn)/Po.
  

If the "Relative" option is selected, the RoR of the base asset will be deducted from the asset's ROR.
If the "SMA easing" option is selected, RoRs will be eased by a simple moving average of "Offset" bars.

Return calculation was wrong, also fixed labels.
