A maximum bid may be specified for each reseller

Each reseller may specify a maximum bid in the appropriate currency. When ABU calculates a new bid for a campaign, it may not exceed the maximum bid setting. This setting's value should be less than or equal to the Google API maximum (that is specified in the AdWords API properties file).

In addition, the default bids for the following currencies should be updated as follows:

USD: 0.60
GBP: 0.30
JPY: 30
CAD: 0.60

Demo:
Set a bid just below max bid cap for abu
Run bid update to increase bid
Show that it doesn't go above the max bid value.

Testing:
Verify that the default bids are correct for each currency
Verify that calculated bids that exceed the maxBid setting are reduced to the maxBid
Verify that if the maxBid exceeds the Google API maxCPCBid bids equal to the maxCPCBid are sent to Google
