From the discussion on #1013:

Since the rule in VS is packages/*, the fact that it contains a slash means
that it is anchored to the top level. That is, is will only apply to
a directory called packages at the top level, and not to any at deeper
directories like App_Data. So these rules at the bottom of your changes
actually aren't necessary after all. I just confirmed this with a quick test.

Support for Phalcon, a PHP Framework

Manually fixed up the rules in the original PR to be consistent with our
omission of the trailing asterisk elsewhere. Fixes #846.

This is #921 without the addition of editor-specific rules.

The original ignore was far too general and results in eliminating packages
named "db" or "project", for example. These are not that uncommon for package
names. Fixes #921.

[Objective-C] Comment out CocoaPods rules

This commit adds a global ignore file for SlickEdit, a commercial editor.

SlickEdit will create the following files when the user sets up a workspace:

*.vpw       Workspace file. Contains a list of project files associated with
            the workspace.
*.vpj       Project file. Contains the project’s settings, including the list
            of source files.
*.vpwhist   Workspace history file for Windows. Contains user session
            information (list of open files, debugger breakpoints, etc.)
*.vpwhistu  Workspace history file for UNIX/Linux/MacOSX. (Same as above.)
*.vtg       Workspace tag file. Contains a database of source code symbols.

It is assumed that GitHub users will generally not want to store their
workspace and project files in a repository, so those files are ignored
globally.  However, those files do not contain user-specific data so they
could be stored in a repository and shared among developers if desired for
a particular project.  This can be done by adding rules like ’!*.vpw’ and
‘!*.vpj’ to the project’s .gitignore file.

The workspace history and tag files contain user-specific data, so they
should not be stored in a repository.

For more information, download the PDF user guide from:
http://www.slickedit.com/products/slickedit/product-documentation

Note: The user guide is 1400 pages long and over 13MB in size.

Searching for ‘vpwhist’ will lead to the section that discusses storing
these files in a repository.

We shouldn't be ignoring these, it's down to the user and we shouldn't enforce them to ignore the `Pods/` directory

http://guides.cocoapods.org/using/using-cocoapods.html#should-i-ignore-the-pods-directory-in-source-control?

http://www.packer.io/

- add the `build/` directory to the .gitignore list (now created by pub).
- add the `.dart.precompiled.js` files (created by dart2js) to the ignore list.

And, sort and re-order the file.
