colorized feedback texts of the script
forgotten feedback's colors :P
the colors for the feedback's colors
missing bracket
removed all the \n: much cleaner
one more \n left
question() needs \n actually to be splitted due to echo -n flag
typo
check if log dir exists or create it
bug in if/else logic
check if log dir exists else create it
implemented some logging with actual function
dest_dir() refactor
just made tidy
adjusted log() usage after refactor
implemented test_rdiff()
misunderstanding ;)
for test_rdiff is better to not open a subshell
renamed constructor in conf_parser
added check if zero hosts configured in conf_parser()

and moved away from inside backup()
