substitute Hash::Merge::Simple with Hash::Merge

Reviews on CPAN suggest, that Hash::Merge::Simple has issues that can
lead to endless looping. To prevent this, we move to Hash::Merge which
seems to work better with circular refs.
[FIX]: alternative config files

A default configuration for Tapper is provided with the Tapper::Config
module. This default config is absolutely necessary to have
configurations for tests at installation. Usually, the default config
won't meet the needs of the user. Therefore, a user can have his own
config. To reduce the config effort user config elements overwrite
values in the default config.

Handling of user config files was not very sane. You could only have one
additional config and for testing, some of them still were ignored. Now
the following config files are evaluated in order, each overwriting all
earlier settings:
* /etc/tapper.cfg
* $ENV{HOME}/.tapper/tapper.cfg
* filename given in $ENV{TAPPER_CONFIG_FILE}

No special care is taken for testing.
