Revision 163743

o Fixed bash scripts (cygwin option was being tested incorrectly, and resulting in no such file: cygpath)
o Changed POM handling to use ArtifactMetadata API rather than direct Artifact construction for POMs
o Streamlined ArtifactDigestor to avoid use of byte arrays for transfer between methods (resulted in a bit of cut-and-paste code, but should run better)
o Pegged OutOfMemoryError to the ArtifactDigestVerifier/ArtifactDigestor combo (motivated the previous change)
o Cleaned up artifact source-file checking before creating any of the target directory structures
o Maybe works, maybe not...will resume testing tomorrow or the next day
