Added sorting
Edited space between columns because of sorting icon
Created SettingsPresenter  (and some changes about redirecting because of it) and basic support for access password - but works only for the one directory, needs to be rewritten.
Because of access password there was need to change some things - path and fullPath are now private and needs to be accessed only by set/get methods.
Also, access password is not longer passed to childrens/parents, but the system needs to go through all chain from bottom to top to find if there is any.
Now password detection works correctly (or should).
Gallery and list view renamed (showed text) to "only images" and "all files" to be more clear.
