Tidy up the code

* fixed compiler warnings, added -Werror to CMakeLists.txt

* removed LibXml2 and boost stuff from CMakeLists.txt

* fixed some things cpplint.py complains about:
  * make single-argument constructors explicit
  * add space before if/for/while/...
  * don't put { on a line of its own
  * remove space after ! operator
  * add space between // and comment
  * remove extra space before ( in function call
  * remove extra space before )
  * shorten lines to <= 80 characters
  * remove blank lines at the start of a code block
  * maybe others
