SliTaz Repositories

Small improvements and fixes:
1. cook: summary(): skip unpackaged packages (when use CATEGORY="nopack");
2. modules/compressor:
a) move strip_package from "fs" to "install" stage - from this moment files in $install and $fs are identical (of course, if you use genpkg_rules() only for copying) - we may clean taz/*/fs/ in the future;
b) remove "empty" *.mo;
c) skip silly error messages when $install or $fs absent;
3. modules/pack:
a) move symlinks *.so to the @dev;
b) small improvements;
4. doc/cookopts.txt: small update;
