The modelines added match the emacs lines already present and also set
the filetype to sh (just like the emacs lines).

Previously, there were many indentation styles in use: Real tabs, 2, 3
or 4 spaces, mixing these within the same file, function or even within
a single line.

This commit changes all bash scripts in the handlers, src and lib dirs
to use consistent indentation: three spaces are now used everywhere.
Other files (e.g. Makefiles) are left untouched.

Additionally, this commit removes all trailing whitespace.

made mktemp a requirement for building backupninja, added autotools variables to substitute the proper binary location and removed bad fall-back when mktemp was not there

than Debian's. Also added Anarcat to the AUTHORS file

 Start to move common functions (maketemp) to lib/tools, and better use autotools for lib/{easydialog,tools}.

 Moved easydialog.sh to lib/ directory: more code is going to be shared, let's start here.

 easydialog: add optional third argument to booleanBox, to set default no if needed (and actually needed by the upcoming dup.helper).

 Fix formDisplay to reset $REPLY as it should.

 Fix listBegin/listItem/listDisplay to work with checklist boxes, as advertized.

added more verbage to ninjahelper
added some IFS=$'' to easydialog
(this allows you to pass through blank lines).

added .disabled
