hooks/initscripts: ditch.
configs/globals: move definitions to scripts/* and load scripts before hooks.

- move
packages/export: check for rsync and git.
packages/fs: check for filesystem tools.
scripts/shell{,.utils}: rename to runner{,-parts}.
packages/{ask,text}: move to scripts.

They don't depend on external tools.
scripts/globals, framework: rip out the braindead so-called bootstrap (a canonical example of primitive overengineering). Stupid me.
