Install fails without -AllowClobber

[bartecargo]

The installation instructions imply that Pansies is optional:

NOTE: If you don't have my PANSIES module for ANSI Escape Sequences, you may want to install that separately

However, I'm unable to install the PowerLine module because it appears to want to pull in the Pansies module, yet I don't want to clobber Write-Host:

C:\WINDOWS\system32> Install-Module PowerLine                                                                          
PackageManagement\Install-Package : The following commands are already available on this system:'Write-Host'. This
module 'Pansies' may override the existing commands. If you still want to install this module 'Pansies', use
-AllowClobber parameter.

I can clarify that in the docs, but you're right, PANSIES is not optional.
It does a lot of the work of dealing with colors.
Additionally, it's Write-Host is fully backward compatible and is faster than the built-in Write-Host.
