Ignore mkdocs site directory

The presentation software pdfpc [1] (which is handy for latex beamer slides) supports additional notes on the secondary screen provided by *.pdfpc files.
These can be autogenerated from latex documents with the pdfpcnotes package [2], thus should be ignored in a latex project (but not in others where they could have been created manually).

[mkdocs](http://www.mkdocs.org/) is rising as an alternative to Sphinx for project's documentation. The default build command puts the generated documentation in a `site` directory at the root of the project which should be ignored.

Fix macOS Icon

.project and .classpath should be inside VC

From the Eclipse Documentation: "Make sure that the .project and .classpath files are under version control. These files must be stored in the repository so that other users checking out the projects for the first time will get the correct type of project and will get the correct Java build path." - http://wiki.eclipse.org/FAQ_How_do_I_set_up_a_Java_project_to_share_in_a_repository%3F

Drastically simplify .gitignore for Dart

Add Cursive's REPL history file

**Reasons for making this change:**

The file `replstate.xml` contains the history of the Clojure REPL
that Cursive adds to IntelliJ. Obviously that's user-specific,
and not relevant to other users.

**Links to documentation supporting these rule changes:**

This file is not well-documented, but in cursive-ide/cursive#1325,
the Cursive developers state that this is the REPL history file,
and that deleting it is acceptable troubleshooting if it's
causing trouble.

remove extra line

Our typical workflow has JS and related build outputs in the `build` directory.

Most users are on new SDKs, so we don't have to worry about these ignores.
Most users don't generate docs locally. If they do, it's easy to add the entry to their .gitignore later.

The PakBlacklist-<BuildConfiguration>.txt is used to disallow some files to be packaged in the pak file.
This can be very helpful to reduce pak file size for mobile platforms.

To avoid the user-defined blueprint class Debug.uasset located in Content/Blueprints folder to be packaged in shipping build, one has to do the following steps:
1. Create the PakBlacklist-Shipping.txt file in Build/Android directory.
2. Insert the content "../../../MyGameName/Blueprints/Debug.uasset
3. Package the game

This .gitignore is not correct. At least was not working for me.
Ignoring /media/* and then excluding !/media/customer/.htaccess is not
working. According to the Git manual, "It is not possible to re-include
a file if a parent directory of that file is excluded."
(https://git-scm.com/docs/gitignore).
