LDCheck - part checking program (1.0)

[Santeri Piippo]

Hej Teemu, may I ask for some more checks in your checking tool?

There are some lines which frequently slip into parts which get uploaded to the PT,
we should prevent the upload directly in such cases. They are:

(1)
the following lines frequently automatedly get inserted by MLCad:
0 BFC CERTIFY INVERTNEXT
0 ROTATION ...

(2)
the following line is an old-style comment
0 WRITE some comment goes here
which nowadays gets written
0 // some comment goes here
so we should prevent upload of files which contain 0 WRITE

(3)
lines with prefix
0 !LPE
are LD Part Editor commands which are not allowed in official files on the PT

(4)
lines with prefix
0 !LPUB
are LPub3D commands which are not allowed in official files on the PT

Hey, that is already done:

Line 9: unknown or deprecated metacommand: BFC CERTIFY INVERTNEXT — HOLD
0 BFC CERTIFY INVERTNEXT
Line 10: unknown or deprecated metacommand: WRITE writings — HOLD
0 WRITE writings
Line 11: unknown or deprecated metacommand: ROTATION 1 2 3 — HOLD
0 ROTATION 1 2 3
Line 12: unknown or deprecated metacommand: !LPE things — HOLD
0 !LPE things
Line 13: unknown or deprecated metacommand: !LPUB more things — HOLD
0 !LPUB more things
Line 14: unknown or deprecated metacommand: STUPID METACOMMAND — HOLD
0 STUPID METACOMMAND

"0 //..." is interpreted as a comment, everything else has to be an official metacommand or it gets complained about.
