Shortcuts with plus sign in .jgorc don't work

[ctrueden]

jgo ome:bio-formats-tools:loci.formats.tools.ImageConverter+org.slf4j:slf4j-simple

successfully runs the program and prints the usage instructions.

But creating the following ~/.jgorc file:

[shortcuts]
bfconvert = ome:bio-formats-tools:loci.formats.tools.ImageConverter+org.slf4j:slf4j-simple

and running:

jgo bfconvert

parses it incorrectly and generates a faulty pom.xml, so the Maven bootstrapping fails.

(The jgo.sh shell script does not exhibit this bug.)
