Add ignore for STS's .springBeans file

Added a forgotten IDE to the .gitignore documentation.

Why?
For completeness and correctness

What?
[Webstorm](https://www.jetbrains.com/webstorm).

Since that is what it should be called now a days according to https://dev.twitter.com/fabric/android/integrating

Updated the tags ignore to include the .tags file. The main reason behind this is because Atom's symbols-view (https://atom.io/packages/symbols-view) supports tags/.tags/TAGS/.TAGS. Therefore, I thought it was a good idea to add the .tags/.TAGS to the ignore list.

Starting with 0.8.0, VS Code will store its settings in a .vscode folder and no longer in the generic .settings folder.

The specification for the .hg/ folder is simplified, see:

which make it easier to find in search

some details based on #1221

This new version adds:
- fsdb waveforms

- vc_hdrs.h
- Also added a few comments about where each one of the files come from.

JetBrains recently released a new C/C++ IDE: CLion

.ensime_cache is cache dir.

In addition to `.Spotlight-V100` and `.Trashes`, the following dotfiles
may appear at the root of all OSX volumes (not just external disks):

- `.DocumentRevisions-V100`: auto-save and versions storage
- `.fseventsd`: file system event storage
- `.Temporaryitems`: temp directory used by some applications instead of
                     /tmp and /var/tmp
- `.VolumeIcon.icns`: storage of custom icon for volume, if set

Whether to use VCS or any other simulator is a choice of the individual designer rather than of the project as a whole.

Ignores all .rdb files, (default: dump.rdb).

These files contain a binary representation of the in-memory
redis data that is generated using cli tools or on a redis
failure.

They can be used to restore a redis db, and may contain
sensitive data so should not be saved in version control.
