Remove the default paramters

[jschpp]

Since all of the following are default values I don't see the need to name them for every parameter. In my opinion It makes it more readable to not specify them in this case.

PS C:\> [parameter]::new()


Position                        : -2147483648
ParameterSetName                : __AllParameterSets
Mandatory                       : False
ValueFromPipeline               : False
ValueFromPipelineByPropertyName : False
ValueFromRemainingArguments     : False
HelpMessage                     :
HelpMessageBaseName             :
HelpMessageResourceId           :
DontShow                        : False
TypeId                          : System.Management.Automation.ParameterAttribute

I've created a PR to this end. I kept Mandatory even if the default of $false was used
