Add full name to account and use it to create commits (#125)

The Git practice is to use the full name when creating commits, not a
user name. This commit fixes that by introducing a fullName field to
Account and using it when creating commits.

For migrating from earlier versions, the user name is used as an initial
value for the full name field.
