Added settings to change output locations

[mhco]

Summary

Added "minify.jsSavePath", "minify.cssSavePath", and "minify.htmlSavePath" settings that enable the user to define where they want files saved. These settings take strings, and can be relative or direct.

This change needs to be thoroughly tested by others before it's fully ready to release.

Examples

Relative:

"minify.jsSavePath": "../../public/js",

Root level:

"minify.cssSavePath": "/assets/css/",

Literal:

"minify.htmlSavePath": "compiled/css/",
