RAD-174 Cleanup smells and style
* remove unused imports
* use final if variables are only assigned once
* add class javadocs to utility classes
* add private constructor for utility classes with only static methods
* use ! isEmpty() instead of size() > 0 on collections
* avoid if/else statements without curly braces
* remove some magic numbers
* make class member a local variable if only used in one method
* use constants for request mapping and view and use class level requestmapping
* declare logger as private static final in classes
