Added a Select-*box alias for Get-*box cmdlets
Fixed a bug where the message's flags were not being updated when using Update-Message
Implemented the -Unread and -Unstar parameters for Update-Message
Capitalized gmail.ps.psd1
Removed the -Last parameter from Filter-Message

Instead of using -Last, the result of Filter-Message can be piped to
Select-Object -Last n
Exported the Move-Message function
Removed the Get-Inbox function and generalized the Get-Mailbox

Using Get-Mailbox w/o any parameters is equivalent to the old Get-Inbox
fucntion. Get-Mailbox also supports the "All Mail", "Starred", "Drafts",
"Important", "Sent Mail", "Spam" folders, and labels
Fixed the README.md formatting
Updated the Move-Message function to support both labels and mailboxes
Message labels are now managed by the Label cmdlets

When a message object is passed to:
	Get-Label	-	all labels applied to that message are returned
	Set-Label	-	applies a label to the message
	Remove-Label	-	removes a label
[Fixed] Get-Mailbox was requiring atleast -Name or -Label parameter
Made the Set-Label's -Name parameter positional
Added information about the new Label functionality
