Fix IntelliJ IDEA configuration wrt SoyParseInfo generated sources
Fix IntelliJ IDEA configuration wrt SoyParseInfo generated sources

net.ltgt.apt plugin changed output directory from generated-sources to
generated/source and updated the IDEA configuratino accordingly, meaning
that generated-sources was now excluded.
Changing the generateSoyParseInfo outputDir to generated/source fixed
this issue, and I went a step farther so that this directory is seen
by IDEA as generated-sources folder.
