* Avoid redundant directories
* Added workflow to validate installer setup
* Added CLI options to locate log file, pid file and cache directory
* Fixed an issue where build command did not support the xdg/system switch

browse_songs wasn't returning any results as in the database they were
save without the trailing slash.
Add two complementary output messages in case of errors trying to
create SharedData and SharedConfig where on Linux XDG defaults to
readonly system wide paths based on XDG_CONFIG_DIRS and XDG_DATA_DIRS
default values from spec (/etc/xdg and /usr/share for example).
And a minor change in the api to use forward slash.
