Correct misspellings and rewrite dpkg subroutine

The Finfosys.class file defines a subroutine for counting the number of
installed packages. For systems using `dpkg` it used grep + wc to
manually parse internal dpkg database files. This is ill-advised as the
dpkg API is constantly evolving and the calculation can be easily
replaced with the `dpkg --get-selections` command, providing an
identical result but by using a stable API call. This resolves the
final lintian warning for the package,
"W: i-nex: uses-dpkg-database-directly usr/bin/i-nex.gambas".

Also, several source files misspelled the word 'needed' as 'nedded' and
the .png icon files from the preceding commit were optimized using
optipng.
