The project description file.

Since IntelliJ 2019.3 this file appeared in our git changes. It seems these are just cached information about remote repositories that are defined in Maven/Gradle.

In our IntelliJ projects where we are using Gradle, the file .idea/compiler.xml and files inside the .idea/artifacts folder are automatically generated by IntelliJ based on the Gradle build model. As these files are generated, they should be ignored in version control.

Added ignore for workspace files (*.code-workspace). They can be added in any directory, depending on the user's preferences.

.svg files are more often than not vector files. You need to exceed 36 swap files for a .svg file to come from Vim.

from vim's documentation on `:mksession` (:help :mksession):

 ...

 10. If a file exists with the same name as the Session file, but ending
     in "x.vim" (for eXtra), executes that as well.  You can use *x.vim
     files to specify additional settings and actions associated with a
     given Session, such as creating menu items in the GUI version.

we already have Session.vim ignored.  the Sessionx.vim file, like
Session.vim, is a user file.  a user would generally want that file kept
private or for themselves, and the public or a team fetching from or
sharing the repository generally have no interest in a file relevant
only to a particular user.  so it's a good idea to get git to help us
avoid mistakenly sharing the file.

Actually, the log generated by debug mode is *.log
i.e. ubuntu-xenial-16.04-cloudimg-console.log

When IntelliJ project is created as a file-based (i.e. without `.idea` folder, but with `.iws`, `.iml` and `.ipr` files), and this is a Gradle or Maven project with auto-import, should ignore them as well for the same reason we ignore `.idea` folder content in that case.

Netbeans Linux and Windows Makefile-*.mk and Package-*.bash files in nbproject directories are automatically generated during compile.  These files are continually updated, which can cause a long list of unnecessary files to add, commit, and push (or that are Untracked).  This has been experienced for Linux and Windows C++ projects.

If checked the option "Always create backup copy" under Settings -> Save within Microsoft Word 2016 on macOS, when editing a docx file, a folder named as same as docx file name(without ext) will be created and placed a docx backup file named "Backup of DOCX_ORIGINAL_FILENAME.docx".

contentModel.xml is automatically generated and can be safely ignored.

Updating file to match the one for swift and objective c.

Add extra commented section to use when using Gradle or Maven auto-import.
These are mentioned in the original reference for optional excludes (https://intellij-support.jetbrains.com/hc/en-us/articles/206544839).
If this would be better as a separate, non-commented ignore file, let me know and I will resubmit.

.idea/misc.xml used to contain usage statistics.  This was broken out to usage.statistics.xml in the latest EAP (2018.2 EAP).  It should be excluded from git.

See https://youtrack.jetbrains.com/issue/IDEA-192913

ignore dbnavigator.xml

because it contains sensitive data, such as host, port, db, user name, and so on.

Microsoft was announced a new extension of installer for Windows. I just added that one to be ignored as default, like others installers files.

Since IDEA 14 (2014), IDEA and other contemporaneous JebBrains IDEs don't store sensitive info in `datasources.xml` and it makes sense to version control to share project data sources among the team. `dataSources.local.xml` is user-specific: contain usernames and could be sensitive from a security perspective, albeit passwords could be externalized to e.g. Mac Keychain.

On line 1, WebStorm is capitalized the same way as the other IDE names.
