Because on DVCS with branches, history is not always linear, we must stop
using increasing integer for revisions because they cause too many conflicts
and a higher revision number does not necessarily means the a BT newer.
They're now a cryptographic hash of all the contents of the Business Template,
and they're computed automatically:
- by genbt5list
- at download
- at building (by default)
- at export

- stop using chdir
- make logging to stdout/stderr optional
- generateInformation: return a StringIO instead of writing to a temporary file

Checked following occurrences in comments:
- "Python 2.[456]"
- "Zope 2.[891]"
- "BBB"
- "BACK"

Checked uses of:
- email, hashlib, numpy & tarfile (modules)
- ImportError
- string.Template
- suppress_events (parameter of _setObject)

Excluded:
- some forked modules (MailTemplates, PortalTransforms...)
- some i18n compatibility code

Oops. Use of & instead of - (to avoid bugs if umask contains 1 in unexpected places) requires to invert mask beforehand.
