[Ids-devel] comment filter patches to 0.6a

[Anthony A. D. T. <aa...@ve...>]

Here are patches to 0.6a that implement an embedded comment filter -- a
configurable regexp to be removed from embedded comments.  This is so that
browsers don't have to see strings like

 CREATOR: XV Version 3.10a  Rev: 12/29/94 Quality = 60, Smoothing = 0

as part of the embedded comments as displayed on the image page.  I've
factored out the Canon/Sony camera-specific strings that were previously
hardcoded in the code and made them part of the default value for
embeddedFilter.  In the future I may extend this into a general-purpose modifier
for embedded comments, allowing one to specify a sort of template, printf-style.

Please forgive me if the patches are malformed.  I haven't done this in a while.
