Add-CloudServer now supports multiple Personality files

When creating a server using the Add-CloudServer command, you can now
specify up to five files to be placed on the server using the API's
"Personality" parameter. NOTE: I *HAVE NOT* yet added any parameter
checks to: 1. See of the source files does, in fact, exist; 2. See if
greater than five files are listed.

An example:

Add-CloudServer -ServerName "MultiFiles" -FlavorID "performance1-4"
-RegionOverride 'DFW' -ImageID "2d4ee06e-d567-47f8-b745-8d281fe5729a"
-Account "demo" -File
"C:\\cloud-automation\\bootstrap.cmd=C:\Users\foo\Documents\WindowsPowershell\Modules\PoshNova\bootstrap.cmd",
"C:\\cloud-automation\\bootstrap2.cmd=C:\Users\foo\Documents\WindowsPowershell\Modules\PoshNova\bootstrap2.cmd"
