part of #705
- copy the files but then remove the temporary ones
- moving instead of copying was problematic due to moving across devices
- still need to convert code to using promises
- Made a helper called ghostScriptTags that will spit out the relevant
script tags with version parameter; 4 unminified files in development,
1 minified file in production.
- Added grunt concat and uglify tasks to build files into core/built
- Fixed some unit tests by making them native date objects
closes#370

- Added field to change post slug (permalink) using existing slug
validation
closes#619
- check if uploaded image name exists in month/year path
- if unique then save
- if not unique then add -1 to the end of the name eg. image-1.jpg
- if image-1.jpg exists then increment to -2
- keep going until a unique name is found
- uses tail recursion as normal path will be to save the first filename and deep recursion will be the exception
- (the alternative of loading the names of all the files in the directory could result in a large in memory array)
