Changed the default denom to mycoin

[phomer]

Set the default denom to mycoin, so that the tutorial tx send works without specifying denomination.

Where in the tutorial was the error being generated? I thought that within all the of the tutorials it now in the form --fee 1mycoin and nolonger --fee 1 --denom mycoin I'm concerned with the idea of not specifiying the denom within the tutorial I think that's a concept we want to introduce right from the get-go, maybe a better explaination of multi-coin abilities of basecoin in the tutorial is more appropriate that modifying this code to assume which coin you want to use if you haven't specified one. Just and idea, thoughts?

Sorry Rigel, it was my mistake. I was looking at the master versions, not develop. Github newbie mistake...
