add support for eps figures

Here is a proposed patch that adds support for using .eps images as the source for generating (using "convert") the .pdf and .png images needed for the documentation. The previous methods being used for .dia sources is preserved, as well as the possibility of providing both .pdf and .png sources.

The reason for this patch is that currently the only way to go when a .dia source is not available (say that the image was generated with another tool, which happens quite often in practice, especially for result plots) is to provide both a .png and a .pdf file. With this patch, now it is sufficient to provide a single .eps source. Additionally, we note that .eps is quite popular for scientific papers, hence supporting .eps images makes it easier to cut and paste documentation to and from scientific papers.

No example usage is included in this patch, but you can find one here:
