add "AutoHotkey Library Distribution"

[joedf]

I suggest adding "AutoHotkey Library Distribution" under scripts. Markdown:

## AutoHotkey Library Distribution

* [pAHKlight](https://github.com/hi5/pAHKlight)
* Ryan Shipp's [ahk-libs](https://github.com/rshipp/ahk-libs)
* [ASPDM](https://github.com/ahkscript/ASPDM), for
  [package/stdlib distribution and management](https://trello.com/b/XVP4M76d/package-stdlib-distribution-and-management)
  from the [ahkscript](https://github.com/ahkscript) folks
* [ALD](http://libba.net/) (discontinued)
* tuncay's original [ahkstdlib](http://www.autohotkey.com/forum/viewtopic.php?t=54996) (discontinued)
* [Salt](https://code.google.com/p/salt/) (discontinued)
* Uberi and infogulch's [ahklib](https://github.com/ahklib)

@aviaryan @joedf @rshipp @mmikeww I edited CONTRIBUTING.md according to the discussion in this issue. Please make comments if you think something should be changed.

@aviaryan @joedf @rshipp @mmikeww If we keep name "Library Distributions", then we have no demand in "UnCategorized" subgroup in "Libraries" group. All package systems, library collections (same as multicategorical libraries) should go to "Library Distributions". Lets try without UnCategorized subgroup in "Libraries" group. If there will be demand in "UnCategorized" subgroup in "Libraries" group we can recreate it later. Any suggestions, ideas, opinions?

If the table of contents expands, changes etc this might but a useful script to keep at hand https://github.com/hi5/InsertTOCintoMD (AutoHotkey script to add a Table of Contents to a Markdown document) - btw I don't suggest it to be added to the list as it has fairly limited use but I find it useful for larger documents.

@hi5 Interesting. I will look at https://github.com/hi5/InsertTOCintoMD . If it is useful for for larger documents I think it is good candidate for our list.

@vasili111 this branch can take the alternative anchors into account https://github.com/hi5/InsertTOCintoMD/blob/dev/InsertTOCintoMD.ahk but the headings would have to be changed slightly like so https://gist.github.com/hi5/d3c4483b229de70760d5 (don't copy this as I've used some weird test examples like qwerty :a: and hellokitty :cat: - but I wouldn't include the script itself in the list

Looks like this was added to contributing.md, can the issue be closed now?

[vasili111]

I think yes. If someone will need we can reopen it.
