This fixed some test failures where openscad would pick up the wrong
font from a system path or not pick up the font at all.

Also remove the path "Fix-path-discovery-for-fonts" - this patch was
accepted upstream at one point and then later made obsolete by later
changes.

And avoid colon (:) in test directory path, as that also causes
failures in a number of font-related test cases.

Add a default exclude pattern in openscad-testrun for tests that cannot
work, as explained in README.testsuite.

This is a reformat-only commit, to facilitate `git-buildpackage pq`
for maintaining debian/patches. No actual changes to packaging in this
commmit.

Newer debhelper no longer puts the -nocache argument to qmake, so
dh_auto_configure can be used without problems.

Version is simplified accordingly.

copyright updated based on the one in openscad-mcad package

The openscad build system expects YYYY.MM-RC1 and fails if it gets the
YYY.MM~RC1 style we use in debian to get correct version comparison order.
So re-write the version before passing to qmake.

Relevant changes were cherry-picked from Maintainer's apparently unreleased
2015.03-2+dfsg-3. This commit adds the relevant descriptions to the
changelog.
