Handle URLs with parameters more sensibly.

Shellquote is the closest thing to array-of-arguments exec calls puppet
supports. As far as I've ever been able to test, it correctly handles quoting
for the shells Puppet uses for `exec{}` resources. Using it to construct
`curl`/`wget` commands means that they correctly download, for example, Jetty:

    http://eclipse.org/downloads/download.php?file=/jetty/stable-8/dist/jetty-distribution-8.1.14.v20131031.tar.gz&r=1

Without shellquote, the `exec` resources see the embedded `&` near the end
and generate two shell commands (the second of which is `r=1`). With
shellquote, the URL is kept as a single argument.

Removed puppet-staging.iml file related to intellij
Add default Windows support

Previously, the hard-coded default staging path of "/opt/staging"
precluded touch-free use of this module on the Windows platform. This
commit adds the params pattern in order to allow the module to work on
Windows platforms without modification.

Further development would be a nice-to-have in terms of adding support
for downloading various kinds of URLs; this is just the critical fix.
Use custom fact to determine staging directory.
Modify staging to support multiple OS.

* Detect %SYSTEMDRIVE%\ProgramData for Windows.
* Use different default for Windows.
Added needed escape characters for variables within string

This is because on Solaris, wget is available in the non-standard path
/usr/sfw/bin as a last resort.
