fix: move set_debug_mode to kugetsu-config.sh

The queue daemon crashes with 'set_debug_mode: command not found'
because cmd_continue() calls set_debug_mode(), but that function
was only defined in the main kugetsu script.

Instead of duplicating the function, move it to kugetsu-config.sh
which is always sourced before kugetsu-session.sh in all contexts.

Fixes #207
