* Added more offline functionality, such as skipping package search
* Disabled list_mirrors() from going online if --offline is given. Defaults to /etc/pacman.d/mirrorlist instead.
* Forgot import of pathlib
* Made list_mirrors() open /etc/pacman.d/mirrorlist in byte mode to better emulate the result of urllib response reading.
* Forgot variable declaration
* Made list_mirrors include activated server definitions
