Qbit Snap Versions Save

Fix for backups not running

Thanks to @juanfra684 for adding some sanity checks and new features!

Changes:

• Support for https and ftp mirrors.
• Default rc.sysmerge and rc.firsttime.
• Various bug fixes

A few fixes, a few changes! Thanks to @cryptorick and @brycied00d for the AFTER feature!

Changelog:

• Allow EXTRACT_ONLY to be specified in ~/.snaprc
• Notify user we are using sysmerge (with -i)
• Use BUILDINFO when available
• Warn user when mirror has the same version as is currently installed
• Fix setting VER in ~/.snaprc
• Add ability to specify an AFTER script in ~/.snaprc, this will be copied to /etc/rc.firsttime
• Fix armv7 snapping

This release has the ability to do an integrity check on itself. Future releases (and master) will all be signed.

Forgot to bump the release number in snap

Thanks to @brycied00d, @elalonde and @Pyrohh for various fixes!

Changes:

• Ability to sign / verify snap.
• Commented lines in snaprc are now ignored.
• Only sysmerge when explicitly told to.
• Check for existence of public key before verifying signatures of sets.
• Make an emergency bsd.sp on MP systems.

Fix for -u being broken. This was caused when -C was passed to the ftp command within the check_update function.

This is also the first release that can itself be verified with signify!

After installing snap.pub in /etc/signify, one can run the following command to verify your install of snap:

cd dir/snap/is/installed
signify -C -p /etc/signify/snap.pub -x SHA256.sig snap

Please use one of the mirrors listed in README.md to verify you have the correct public key!

Lots of clean up from @Pyrohh, you can now pass -C to ftp(1) to allow it to resume incomplete downloads.

Thanks to @elalonde for a full test and report on the -C stuffs! Also thanks to @rockworldmi for suggesting the -C in the first place!

Add ability to reboot after running. Smarter about update flags, now you don't need to do -uU, simply running -U will download the newest version.

Thanks to @elalonde for the PRs!
