Changed basic applyValue generated code to hand written.

Changed custom applyValue code for border-image-source and
-webkit-mask-box-image-source to be hand written instead of generated
with a custom template as the savings on code duplication aren't large
enough to warrant the added code complexity.

These hand written custom methods will be moved to property classes
after all the generated methods are moved.
