Add-setDefaultPerPage Method

[lrljoe]

This adds to the pagination methods available.
Presently setPerPage is used for setting the per-page value
Therefore using it in configure() or similar will over-ride anything defined via the querystring or session

To rectify this, setDefaultPerPage is being added, to be used to set a default per-page value, which will only be used if perPage is the default (10) value, otherwise it will respect what is currently set (e.g. via the session/querystring)
