Code cleanup - whitespaces

- 4-spaces (and not tabs) for indentation.
- no trailing spaces
- 1-space between function name and braces (both calls and signature declarations)
- a newline before each return, break, throw, continue etc. if it is not the only statement in that block.
- empty line between methods, two between classes
- no empty line at the end of file
Code cleanup

- Remove unnecessary code and comments
- Blocks inside if/else must always be enclosed by brackets
- Take care of compile warnings
- Use "var" in variable declarations wherever possible
