shrink-backup v1.1

With this release versioning is changed from x.x.x to x.x

The most noticeable change is the UI with coloring. But small efficiency increases to the code has also been made.

Support for dietPi and webmin. Also created a way to convert your systems ext4 filesystem into f2fs on the img file.
Downside is f2fs can not be resized while mounted unlike with ext4 so the user have to manually expand the img to cover the entire storage medium manually before booting.
Increasing size while updating the img is also not yet covered, but should be doable so this feature will be implemented in a future release.

A loop function to retry 3 times after looping the img file within the script has been implemented because bug reports started coming in about the UUID on the loop not being found, therefore failing the backup.
Giving the system some time seems to resolve the issue.
This seems to be related to if img file is located on a network storage. Usually, but not always, wifi network.

• UI improvements in form of coloring and other formatting
• New funcionality: --f2fs convert ext4 on root into f2fs on img file
• Added support for f2fs
• Added support for DietPi
• Added support for webmin

• Added .gitignore to github repo for users that change exclude.txt and want to use git pull without issues.
