We had inverted logic in wpsc_is_shipping_enabled().  This is why best practices dictate positive flags.
Save data immediately when data map is initialized
* also clear dirty flag when saved
removed debug code
Merge branch 'branch-3.8.14.1' of github.com:wp-e-commerce/WP-e-Commerce into branch-3.8.14.1
Clear temporary data, whether in cache or in transient
* Checks options tables for transients and delete them if appropriate
* Fires action hooks so themes, classes, plug-ins, shipping modules all can know when data needs to be cleared, or has been cleared
* Updated functions to use new clear data function rather than just wp_clear_cache
remember names of transients as they are set so we can clear them specifically
no mass flushing of WordPress cache
handles upgrade automatically by looking at database on first run
Revert 7d4613e7a820c3fcb775c40ae142ca7c6f646ab1 and clean up wpsc_item_process_file a wee bit.  Not sure what I was smoking in #688, but it better have been worth the price of admission.  Fixes #1248
Whoops on that
Regions update correctly on shipping same as billing change
When shipping same as billing changes the country drop downs need to be updated first, then the region drop downs need to be filled with the current correct regions, then the current region needs to be set.

This change enforces this dependency order so that display is correct

Resolves issue #1280
spelling corrections in comments
Fix improper transient flush for 3.8.14.1 branch.
Show region label as placeholder in shipping calculator
If the region label is defined us it as the default placeholder
Merge remote-tracking branch 'upstream/branch-3.8.14.1' into branch-3.8.14.1-dev
