Repr improvement

[lL1l1]

Description of the proposed changes

More FAF-specific improvements to the inspect library:

• Print the base class of a table, if any.
• Don't print __index fields if they're the same as the table. This removes a lot of common recursive clutter (it is still possible to recurse, for example the Brain.CDR.Brain or WorldView.view.WorldView in the example below).
• Print source for lua functions in a rather short local format.

Testing done on the proposed changes

Use this command on a Percival:

SimLua LOG(repr(SelectedUnit(), {meta=true}))

Example Output (Percival).txt

Use this command:

UI_Lua LOG(repr(import('/lua/ui/game/worldview.lua').GetWorldViews()['WorldCamera'], {meta = true}))

Example Output (main WorldView).txt

Additional context

The last version of the original repr printed class-specific data. I was lazy on implementing that, but it could be done by using a helper function instead of directly the names table. Still, in general these changes lay the foundations for class-specific data printing.
