First pass at Issue #39
Improve Sales Log Details view (single view of sales log)
remove 'blank' for addresses to enable copy-paste. changed markup and css for addresses to better reflect blank fields. Changed 'blank' to 'not provided' for other fields. Moved date and order number from Billing Details to subtitle.
Show country name rather than just country isocode. Hide address lines that are missing data. Right align and tidy up summation field labels (tax, discount, etc.).
change country isocode lookups to use WPSC_Country.
show time with date in subtitle of single purchase log
add previous and next pagination to subtitle of single purchase log page
use wpsc_get_country() to get country name from isocode in purchase log
Swap date and time order in single purchase page subtitle. Restyle Previous and Next buttons to reflect design and feedback
remove redundant variable
correctly i18n date rendered in purchase logs
use transient to store max purchase id, and invalidate on purchase log insert.
