accept glob patterns in the source

[alanhoyle]

This is semi-related to #14, but it would also be useful if the source= parameter accepted standard glob patterns like *.txt or prefix.*

I know this works on the unix command line where you can do:

$ rsync *.txt prefix.* /path/to/destination

Hey there, sorry for the long wait.

This project hasn't seen much updates since a long time, but I plan to get back to it, review the outstanding PRs, take a look at the issues and get the ball rolling again.

I'll take a look at what's preventing globs from being interpreted. Maybe it's a matter of setting shopt -s globstar in the subshell, but I'll have to see if I can describe this in a couple of integration tests to make sure nothing breaks. If setting this in the subshell works but breaks something else I'll have to see if I expose this option somehow in the API.
