Add cmdlet to delete default user pinned views

[seanmcne]

, ignore anything else that isn't grid views.

Need to validate supportability & overall impact - that said user default is empty and there is no ability to unpin a view that is non-standard (if a user does it by accident, testing, etc). Changing these settings will force the users cache to expire so doing this on a mass scale may not be advised. Approach I'm thinking of taking is:

1. Get the xml
2. parse into "DefaultGridView" records/collection (verify uniqueness by entityobjecttypecode)
3. Execute deletion from there either by "all" or by a specific ETC #

Clear-CrmUserPinnedViews

#this will clear all user pinned views (no matter what they have pinned) 
Update-CrmRecord -Id $systemUserId -EntityLogicalName usersettings @{"personalizationsettings"=""} 

Remove-CrmUserPinnedView

#this is an attempt to clear the views by entityid - which seems to fail in and of itself, but if you dump ALL of them first, then add the result back, that seems to work 

$etc = 4 #clear out the users Account pinned views entity (otc/etc 4)

$us = Get-CrmRecord -EntityLogicalName usersettings -Fields personalizationsettings -Id (Invoke-CrmWhoAmI).UserId  

$systemUserId = $us.ReturnProperty_Id
$settings=[xml]$us.personalizationsettings
$etc = 2
$node = $settings.DefaultGridViews.SelectSingleNode("//EntityTypeCode[.='$etc']")
if(!$node -ne $null){
    $node = $node.ParentNode
    $node.ParentNode.RemoveChild($node)
}

#Attempt 1 - Successful update - but it doesn't "take" without clearing first
Update-CrmRecord -Id $systemUserId -EntityLogicalName usersettings @{"personalizationsettings"=""} 
Update-CrmRecord -Id $systemUserId -EntityLogicalName usersettings @{"personalizationsettings"=$settings.InnerXml} 

#Attempt 2 also failed
$newSettings = New-Object Microsoft.Xrm.Sdk.Entity
$newSettings.Id = $systemUserId
$newSettings.LogicalName = "usersettings"
$newSettings.Attributes.Add("personalizationsettings",$settings.InnerXml)

$updateRequest = new-object Microsoft.Crm.Sdk.Messages.UpdateUserSettingsSystemUserRequest
$updateRequest.UserId = $systemUserId
$updateRequest.Settings=$newSettings

$conn.ExecuteCrmOrganizationRequest($updateRequest)
