- Fixed Moon image for 4-flash_joy_b
- Two new Nagisa images that are amazing! (6-stripping and 7-stripped)

I shuffled some of Nagisa's dialogue and image assignments to suit these
new replacements.

Moon's orginal images are by DrankeyKrang.

As Kisekae is limited in how well it can display the kinds of things we
want to show in SPNatI, Horsecatdraws has modified some of Moon's images
to better demonstrate Moon's disrobing. The majority of the changed
images are in stages where Moon is making an impression on her shirt,
but he has also drawn her lifted shirt and lowered shorts for several
images too.

Also converted yet more paste-in lines to the new targeting syntax.
Zombiqaz made a couple of fixes to make_xml.py that allow more lines to
be converted this way, possibly allowing ALL paste-in lines to be
converted to behaviour document lines!

Deleted and moved some images as per the following:

- Deleted kisekae set-up images. These are only a byproduct of character
positioning and are not unique or used by the game.
- Altered a few kisekae code text files as per the above to prevent
these from being created again.
- Appended some non-game object images with ".image" to prevent them
being counted as part of our hosting allowance.
- Moved the Miss Pauling example image to the saves folder.
- Deleted the outdated python scripts from Alice's folder.

Also changes the expression for a few existing lines

Bugfix for make_xml.py

See merge request !182

make_xml.py should no longer crash when using a behaviour file with
multi-word target types.

Oops!
