[arch-dev-public] ABS 2.2 release

[Allan McRae]

Hi all,

I have pushed a new release of abs to testing.  The main change is the 
added ability to specify which repos or packages to sync on the command 
line (e.g. "abs core extra/abs") which will be of use to those want to 
sync single packages. 

Other changes:
- Removed unstable repo
- Fixed order of sourcing in rc-script.proto (FS#10833)
- No longer pipes all output to STDERR (FS#10686)
- Added various PKGBUILD and install script prototypes (FS#10274)

I'll move it to extra in a few days provided I didn't break anything...

Allan
