Important update:

- Buffer:
  - fix undefined value: zero terminate buffer when loading from FD
- DataTree:
  - fix memory leak: destroy temporary search path
  - improve delete(): delete all children for member if no path given
  - bug fix: initiate object with 0 length (not -1)
- JSONparse:
  - Remove level parameter
  - Add path to load/save/print methods (print only portion of tree)
  - fix memory leak: destroy temporary object name
