Pending donations using wrong exchange rate

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Someone make a eCheck donation while the exchange rate for donations is
"0.5", meaning 1$ = 2 Credits (For 20$)
2. The eCheck take a couple of days clear during which the extange rate is
change to "1.0", 1$ = 1 Credits
3. When  it clears it uses the current exchange rate rather than the rate
when the donation was originally made (Should get 40$)

What is the expected output? What do you see instead?
When it clears I believe it should use the exchange rate when the donation
was made rather than when the donation actually clears in paypal. This
being useful in donation events, like double credits for a day.

What version of the product are you using? On what operating system?
Idk, some old ass one but I believe the problem still exist in current
versions.

Please provide any additional information below.

This brings up a necessity for storing the exchange rate at the time of the 
donation.
Currently, this is not supported.

Changing to low priority for possible implementation in a later milestone.
