Release 3.0-test2

Warning

This release is tested so that it works properly on the PC side (thanks to the eMMC backup). I unfortunately don't have my Lumia anymore so I cannot test the booting myself.
If there is any problem, please open an issue ticket providing detailed information and logs.

Changes:

• Fixed crashing when user write quotes to the prompt.
• Installer: Ask for storage space instead of hardcoding.
• Minor improvements.

(since 3.0-test)

Todo:

• Per-instance logging: Stuff that's not in the installation process.
