Improve FileActions JS to allow for custom rendering

This improves the OCA.Files.FileActions class to support passing a
"render" function in the action object.

The default function "_defaultRenderFunction" is used by default and
renders actions in the usual actions container.

Moved "Rename" and "Delete" to custom render functions.

Improve the bitmap and vector mime icons

* Vector files such as Illustrator files currently show the "image"
icon. I propose to add a new type to mimetypeIcon() called
"image/vector" and which would be used by SVG as well
* We can use the current image-svg+xml icon, but would simply rename it
to image-vector
* The black and white "image" icon looks too much like a settings icon.
A simple picture representation pasted over the file icon should work
Trim port from domain

Depending on the used environment the port might be appended to the host header resulting in an inaccessible instance when initially setting up on a system with a different HTTP or HTTPS port. (for example test:500)

To test this setup ownCloud under a different port with and without this patch. (heads-up: localhost is always white-listed, so use a different domain)
