Better explanations about the "Receive" address

[dbadol]

As per screenshot, the "Receive" screen says:

• "Sender will be given a choice between regular and offline payment."
• "For online payment to complete, you should get online during 12 hours after coins are sent."

Those two sentences should be adjusted because they are a bit confusing:

1. The first sentence talks about "regular" or "offline" payments, while the the second talks about "online" payment.
2. The second sentence could also be understood as if the wallet must stay online during the whole 12 hours!

I propose to use the following wording instead:

• "Sender will be given a choice between online and offline payment."
• "For online payment to complete, you will need to open and connect your wallet sometime within 12 hours after the coins are sent."
