Tarsnap GUI v0.9 released

[Shinnok <admin@shinnok.com>]

Greetings from the pit,

A fresh mint of Tarsnap GUI, version 0.9, is hot out the forge:

https://github.com/Tarsnap/tarsnap-gui/releases/tag/v0.9

This release improves on the track already paved by the previous release in
terms of performance, code robustness, adherence to modern C++ practices
and UI consistency, adds a bunch of new features as well as numerous other
improvements, fixes and adjustments throughout the whole spectrum. This release
makes Tarsnap GUI more functional, leaner and more robust overall.

Full change-log brought forward by this release:
https://github.com/Tarsnap/tarsnap-gui/blob/v0.9/CHANGELOG

What's new:

1. You can now download an archive as a tar file from the Restore dialog. Keep
in mind that the resulting file is a plain tar archive, no compression.

2. You now have the ability to review your account and machine activity logs,
the same records that you see on the Tarsnap website, from within the app in
Settings -> Account pane. Tarsnap account login is required for fetching the 
activity logs.

3. On a vanilla setup, the application now suggests predefined Jobs for a
handful of commonly backed up directories like Desktop, Documents and Pictures.

4. If you built a Backup list in the Backup pane and then find out that the
list would make a good Job, you can easily turn that into one by using the
drop-down option available on the backup button.

5. Added a global setting for limiting download/upload rates in Settings ->
Application.

Misc notes regarding this release:

1. The OS X Homebrew repo is now the preferred method of installation for
this platform. If you update your Homebrew installation to the latest version,
installing Tarsnap GUI and its dependencies is as easy as:

$brew install tarsnap-gui && brew linkapps tarsnap-gui

2. Port and pkg for Tarsnap-GUI have been available for FreeBSD for a good while
now. Installing on latest FreeBSD 10.3 is as easy as:

$pkg install tarsnap tarsnap-gui

2. SI notation is now the default display option for consistency with the CLI
tools. You can easily switch your notation back to IEC in Settings.

3. The Setup Wizard received some good amount of love with great help from
Graham Percival. The Wizard should now be easier to follow and is one step
less than before.

4. For a tutorial on quickly getting started with Tarsnap GUI using OS X as an
example see:

5. There is no caveat when upgrading from v0.8. Everything should go smooth as
silk, if you encounter issues please report back.

This release is the best offering to date and thus I strongly encourage
everyone to upgrade and follow back with feedback be it either positive or
negative. As always, I'm welcome to new ideas or CLI options coverage requests.

Cheers,
Shinnok
