Function Show-SqlDatabaseList
{
<#
.SYNOPSIS
Shows a list of databases in a GUI
    
.DESCRIPTION
Shows a list of databases in a GUI. Returns a simple string. Hitting cancel returns null.
    
.PARAMETER SqlServer
The SQL Server instance.
    
.PARAMETER SqlCredential
Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted. To use:

$scred = Get-Credential, then pass $scred object to the -SqlCredential parameter.

Windows Authentication will be used if SqlCredential is not specified. SQL Server does not accept Windows credentials being passed as credentials. To connect as a different Windows user, run PowerShell as that user.
    
.PARAMETER Title
Title of the Window. Default is "Select Database".
    
.PARAMETER Header
Header right above the databases. Default is "Select the database:".
    
.PARAMETER DefaultDb
Highlight (select) a specified database by default
