The SHA256 checksum is base64 encoded, instead of the
hexadecimal encoding that most checksum tools default to.

List of noteworthy changes in this release:

* New configuration keywords

** sigterm SIG

Available for use in "component" sections.  This statement defines
signal which pies should send to the running component instance in
order to terminate it.  Defaults to SIGTERM.

* Correct component shutdown sequence

The shutdown sequence is determined taking into account dependencies
between components, so that each component is stopped before components
it depends on.

* Fallback log file

Fallback log file is a place where pies writes out of band log messages,
i.e. messages about not being able to open syslog socket or send logs
to it.  Regular log messages are diverted to this file if syslog was
requested, but cannot be used because of a permanent error.

* Bugfixes

** Fix the operation of "piesctl config reload"

** Fix configuration preprocessing.

** Various fixes in REST API server.

Sergey
