Merge lp://qastaging/~ckamphaus/pasaffe/pasaffe into lp://qastaging/~mdeslaur/pasaffe/trunk

Since I wasn't sure how long the review process and releasing a new version would take, I created a ppa where I could release new versions from my branch:
https://launchpad.net/~ckamphaus/+archive/ubuntu/pasaffe

Changes look good. Thanks!

> Double click on tree item toggles folder expanded state or copies password

I'm really not sure about this one...it's odd to me that double clicking an entry would copy the password instead of opening it, and would probably be surprising to most users. This change I may revert, I'll have to think about it.

> Display username in the tree view item title

I think I'll add an option to turn this on. I don't see the use case for it unless you have multiple accounts on the same system, and adding the username clutters the tree.

> Double click on tree item toggles folder expanded state or copies password

So, I am going to add a new option in the preferences for this one too:

Double-Click [edits entry][copies password]

The reason for most of my changes is that I'm using pasaffe at work and I like my workflows to be as efficient as possible.

E.g. I have some server environments where I have multiple user accounts thus it's very important that I can directly select the right entry without having to go through all of them until I find the one with the right username.
The re-ordering of the context menu and the copy through double-click make it quicker to copy a password. (I notice that copying a password is something I do a lot more often than editing one)
Similarly the additional possibility of using the left and right keys to traverse the tree and collapse/expand folders make it easier to find entries in a big safe.
Finally the clipboard clearing improves the security when exiting pasaffe directly after copying a password. Also the existing clearing of the clipboard through a timer is improved since it does not clear the clipboard if the user has copied something in another program after the password.

I am glad my changes helped improve pasaffe and that you will make the username appearance in the entry title and double-click behavior configurable.

Thanks for the improvements! :)
