Improvements to Stock Exit to Patient receipt

[jniles]

This is what the body of a current stock exit receipt looks like:

Fig 1: Stock exit to patient receipt

A couple pieces of would be welcome:

1. Each line concerns a medication/inventory item. Could we put that in the description of the transaction? For example, instead of "medicaments vendue aux malades", it would be awesome to have "Medicaments vendue aux malades - 20 comprimes de Quinine 500mg".
2. It would be nice to include the patient and pharamacy information in the voucher description. We do this for invoices, for example. Like "Distribution to JNILES (PA.TPA.123) from PHARMACY123".
3. If an invoice is linked, we should put the invoice identifier in the text of the description of the voucher so that we can more easily find it later.
