7 bug external errors

[iptoux]

Done!

All things are back in library/script. Now the whole library is more modular, so future editing and adding of features should be easier. The library had now the following functions:

• (rewrote) bs_error_trap
• (old) bs_debug
• (rewrote/new) error_read_file
• (rewrote) error_merge_vars
• (new) error_stacktrace
• (rewrote/new) error_out_msg
• (rewrote/new) error_out_log
• (new) error_read_src
• (new) error_exit_clean
