Displaying log

[LukasLedvina]

Log displayed by listing directory structure is not formatted (new lines are ignored) but log displayed from building log is nicely formatted.

Idea: maybe set some MIME HTTP header that'll convince the browser to correctly interpret newline characters (now it just thinks it's an HTML document and thus merging all the lines).

Added explicit Content-Type headers to files with chosen file extensions (see b6391b1). Please test and close (hopefully you would not like to add the header to another files :-).
