Updated the pot file for the last changes on the translation generation
script to take effect.
Translation (po) files have been updated to reflect changes on the
template, and translations from POEditor have been synced.
Adds a new `_print` function to print strings without coloring or
other stuff added by the `_msg` function. It's used for the usage
message, letting it be translated.
The usage messages have been split into one-line strings, and added
back to the tomb.pot and *.po files.
Issues:
`gettext -s - "$2"` prints the -, instead of getting the desired effect
The custom expansion missed repeated variables in a single string
Some string fixes
