Improvement: Invoice allocation options more visible

Hi all,

We've recently received a great suggestion by one of our users to move the invoice allocation options such as Credit, FX, Write off from the Options link; which was previously quite hidden to a more prominent position beside the Payment History table:

A big thank you to Simon for the great suggestion! We hope this will help maximise the allocation utility to all our users, who may not have been aware of this in the past.
