General code cleanups

* Use default member initializers
* Use range-based loops
* Don't use 'else' after 'return'
* Removed some unused includes
* Construct empty strings with std::string() instead of ""
* Clear strings with .clear() instead of assigning ""
* Check whether strings are empty with .empty() instead of comparing to ""
* Removed redundant initializations
