Release v2.4.0.1

Minor tweaks since v2.4 (only the .ini files have changed):

• Use consistent settings for a normal Creator Pro (previous versions had tweaks for my specific modified printer).
• Let PrusaSlicer decide on extrusion width defaults.
• Include a PETG filament profile that is safe to use on an unmodified FFCP, although results will likely be poor. See README.
• Tweaks to other PETG profiles (only really relevant if you have the necessary printer upgrades).
• Add more information inside the bundle itself (see ‘Notes’ in PrusaSlicer where available).

If you are upgrading from 2.3 or older, here is an important bit of the 2.4 release notes:

• Configuration has been separated from the make_fcp_x3g.pl script. You should no longer edit the script, only the config text file. See the README for updated instructions.
  A quick checklist for migrating your config lines from the old script to the new text file:
  • Convert single quotes to double quotes.
  • Omit commas in [ARRAY] type items. Put each array element between double quotes and separate elements with a space.
  • No trailing semicolons.

(Changed this release from 2.4.1 to 2.4.0.1 because I will need an actual 2.4.1 release to remain in sync with PrusaSlicer releases.)
