Added simple status current # of how many files.

- Removed white spaces in output.
Fixed bug in lock file declaration.

- added state_file variable as this is used by many of my commands.
Have to add red() in indespensible.sh as as there's no way (that I
know of) to include it relatively when sourcing indespensible.sh from
another script.
Improved user feedback when there's another process running.
Improved remove_pid_and_exit_in_error.
Optimised import-picture by giving it its own state file.

- When it runs, it will check the state file if it at all have ever
  processed the current file and if yes, refrain from doing any
  inspection of it.

- Now uses moria common libraries.
Reintroducing running google command inside  a wrapper.

- Haven't had problems with this lately, so reintroducing it as it makes
  a number of things easier.
