Taming the beast, TUI back to stable

Now after the big excitement of the successfull changes to use an invidiual rc file for all its used variables, basic usage seems to be back to normal again.

-> Taming the beast, back to stable! <-

It is causing a rush to figure one successfully installs the bash completition, accidently to a wrong and non-working path.

But this massive change also helped me to figure out which internal variables to share and which not, so i've added the function 'provides' to figure that out.

tui provides

Will print a hughe and long list with all the variables used internaly and which you may use as well.

If you

source  tui

you'll have all of those variables available, but sourcing just the rc file, and the wanted file providing the variables you want can increase usage speed.

source ~/.tui_rc || . tui
source $TUI_FILE_{APPS,SETTINGS}

Also several small hotfixes, of which i was sure i have had applied already 6 months ago....

Hope you like it, enjoy! :)
