devel: use default-date config field when creating obsmarkers

Also use the default-date when creating obsmarkers. Currently they are created
with the current date and without any option to force their value.

To test the feature, we remove some of the many 'glob' used to match obsmarker
date in the tests.

# BSD 'more' escapes ANSI color sequences by default. This can be disabled by
# $MORE variable, but there's no compatible option with Linux 'more'. Given
# OS X is widely used and most modern Unix systems would have 'less', setting
# 'less' as the default seems reasonable.
