Install script adds menu item, desktop icon, file association for
the current user - even if the Arduino installation was placed
outside of the user's home dir (such as in /opt or /usr/local).
Added three more icon resolutions (64px, 72px, 96px) - by using
the 256px file - maybe there is a better source available for this...
Modified build.xml for copying the existing icons and mime.xml file,
both scripts and adjusted file permissions (ugo+x) for *.sh files to
be executable by others by default.
These are Arduino icons in various formats that can be used by
redistributors in menus etc.
These icons were taken from the Debian package, version 1:1.0.5+dfsg2-1.
According to the copyright file in there, all icons are licensed under
the GPL-2+.
