PowerShell GET/POST to Bitbucket API

I guarantee there is a better way to do this, but it took me a while to find the powershell syntax to do GET/POSTing, so hopefully this helps save someone some time.  And yeah, I'm aware that it's saving the password variable in plaintext.  Something to consider for v2.

The idea behind this (partial) script is that you can get most of the pre-setup done automatically.  One of the issues I haven't resolved yet is automatically accepting the ssh prompts (tried pre-injecting stuff, bunch of other things, no luck).  Not a huge deal since the biggest issue is the POSTing of the ssh key to Bitbucket.

This is a small piece of a project to automagically set up a dev workstation from a bare machine.  I think I'll try to post all of the code up when it's done - seems to be a common issue.

Also, I am really starting to get annoyed w. Blogger's inability to do code snippets.  One of these days I'll fix it...or move to Github gists for everything...
