I wrote a more explanatory comment regarding the cache directory
and why it is ignored.

With SugarCRM 6.4 the `cache/upload` directory moved to `upload` and
`upload_backup`. These directories can safely be ignored.

Additionally the `cache` directory is now ignored completely because it
leads to the behaviour to use the git repository as a kind of backup
tool if several parts of it are included. Furthermore the directory
structure beneath `cache` is victim of enduring changes by the
developers.

I did also some code cleanup regarding the path names e.g. adding a `/`
before most file and directory names.

Slashify Ruby files and directories.

arcresu pointed out that `*.gem`, `*.rbc`, `.rvmrc` might not be at
the top level in a repository. Thus, remove leading slashes for these.

Perhaps this is a little pedantic, but without the initial / all
such matches within the repository get ignored, and without the
trailing slash files as well as directories of that name get ignored.
e.g. Specifying `tmp` and `test/tmp` without slashes is redundant, as
`tmp` already ignores `test/tmp`, as well as every other `tmp` and
`tmp/`.

Prevent Unity .gitignore from ignoring non-Unity project files

Unity only generates project files in the top-level directory.
However, the current .gitignore will ignore all project files even
if they were not generated by Unity.

It is sometimes necessary to include non-Unity project files for
level editors or other utility projects that have been added to the
repository.
