Fix indentation 'Code Injection'

Ignore .pdf

On Windows, when PDF is opened with Acrobat Reader, one gets following output:

    ! I can't write on file `document.pdf'.
    Please type another file name for output:

If one simply presses "Enter" to continue, the file `.pdf` is generated. Since this is a common case and `.pdf` is never used as full file name, this file should be ignored, too.

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.
