Python 3.10, ezdxf 0.17.1, vispy 0.9.0 fixes - fixed for next version

[Adam Sałata]

Python 3.10

https://docs.python.org/3/library/collections.abc.html (depricated since 3.3 removed in 3.10)

• appCommon/Common.py
  change line 22 to import collections.abc as collections
• camlib.py
  change line 41 to from collections.abc import Iterable
• appTools/ToolCopperThieving.py
  change line 23 to from collections.abc import Iterable
• appTools/ToolQRCode.py
  change line 21 to from collections.abc import Iterable
• makefile sorts numbers (python version) alphabetically (10<5)
  not sure how to fix it easily (split by '.' compare each element?)

EzDxf

ezdxf.math no longer has Vector (now Vec3)

• appParsers/ParseDXF.py
  change line 10 to from ezdxf.math import Vec3 as ezdxf_vector

VisPy

I have found in another issue (#534) that you have removed the ++ marker patch but it is still present in beta_8.994

• appGui/VisPyPatches.py
  remove lines 16-34 (inclusive)

After these changes it will start, not sure if it will work properly

[Marius Stanciu]

Those issues are fixed in my working copy and the fix will be in the next release (when released).
