ignore perltidy output files

Ignore *.pid.lock

Some popular applications (for example, Phusion Passenger) leave `*.pid.lock` file(s). For example, when you type `passenger start` with simple express app listening on port 3000, it leaves the following files:

* `passenger.3000.pid` (removed when passenger stops)
* `passenger.3000.log`
* `passenger.3000.pid.lock`

While `*pid` and `*.log` are ignored, `*.pid.lock` remains unignored. Phusion Passenger is quite popular, and `*.pid.lock` file should be ignored.

Update Android.gitignore

Update TeX.gitignore

added prerequisites for C and C++

Add support for easy-todo package (that produces .lod file during the compilation)

Only ignore the build directory in the same directory as .gitignore for Gradle

If you have a Java package with `build` in it, the current version will always ignore files in that directory.
This change makes it so only the root "build" directory is ignored.

I believe that this assumes .gitignore is in the root of a project.

ignore *.VC.db files

Ignore all forms of CMakeLists.txt.user

In addition to *.VC.opendb, *.VC.db file should be regenerated by Visual Studio automatically. So, it makes sense to ignore *.VC.db file too as it's been ignored in https://github.com/github/gitignore/blob/master/VisualStudio.gitignore

In some cases Qt Creator will create a CMakeLists.txt.user file with a short hash which should also be ignored. For example:

    CMakeLists.txt.user.1fa15d5

Create the gitignore for Bazaar version control system

VisualStudio ignore project.fragment.lock.json

Update D.gitignore

Add docs/ and *.lst

I've just upgraded to ASP.NET Core RC2, and I've found that Visual
Studio is producing a file called project.fragment.lock.json. When I
delete the file it is recreated during build. Given project.lock.json is
already ignored this looks like another file to ignore.

add CTestTestfile.cmake into CMake.gitignore

Add sublime-text-3 gitignore for package control

Create Julia.gitignore

After trying this tool for code injeciton: https://github.com/johnno1962/injectionforxcode we added it to our workflow.
Only bad side is that there's a folder included in the project that would be worth ignoring.
We had it in our .gitignore file. Just pushing the change

Add .env to optionally ignored files

Many twelve-factor apps use environment variables rather than the built in Rails secrets mechanism to store secrets.
The [dotenv](https://github.com/bkeepers/dotenv) gem is widely used for this purpose and allows environment variables to be loaded from the `.env` file. However, this file should not be committed to source control.

This PR just adds the `.env` file to `.gitignore` so that these secrets aren't accidentally committed. In some rare instances, it may be required that this file is committed to source control so I've added it to the list of files that can be removed if the developer is ok with secrets being committed.

Ignore '*.DS_Store' instead of ignore '.DS_Store'
