Clarify what commenting *.pubxml does

user passwords are stored in *.user files so it is only database connection strings that are not protected.

https://github.com/github/gitignore/commit/08def965cd1c0241a7cffbe7c26a74b3cab61243 incorrect states that commenting *.pubxml will keep your passwords hidden when it will actually do the opposite. This clarifies what commenting *.pubxml does and warns you of the dangers.

Removed the separate top-level patterns for NuGet in accordance with comments in PR. Will now match version 2.0.1.

Fixed pattern for excluding nuget packages so that it works both for top level package folder and for any lower level package folders.  Re-include patterns fixed the same way.

The Meta Programming System is a language workbench created by JetBrains.

By default this file will ignore the generated java source and the compiled java classes that are
produced by the language compiler. It will only add the Models which contain all information
necessary to reproduce the the java source code and the the resulting class files.

In addition to the generated source code it will ignore the test result files and test property files,
because those are also generated from the models.

The ignore file also prevents commiting the workspace.xml which contains the currently editor state,
like open files and cursor position.
