Hi all!

I'm sorry this EMail is so long, but I hope its worth the read...

I completely revised my patch and approached this in a whole different
manner. The discussion on Aleksi's topics with file version regexes
helped a lot with this.

I have split up the work into several patches since there are some
changes that are useful in their own right:

0003-Whitespace-fixes.patch:
This fixes some whitespaces in the files for the following patches.

0004-Moved-all-file-search-settings-to-single-page.patch:
The settings on how new files are search for and how information is
loaded for this files is intermingled. This patch separates the file
searching and information loading settings onto properly separated
tabs. I think this is useful in general because the settings are
ordered more logically.

0005-Cache-invariant-settings-so-they-are-only-loaded-onc.patch:
There are some strings and regexes that are constant throughout the
NewImageFinder::loadExtraFiles() loop, this patch pulls them out and
creates them only once. As with 0004 useful on its own.

0006-Support-multiple-replacement-regexes-for-file-versio.patch:
This patch creates support for several regexes for the original file
version detection. Those regexes are separated with semicolons and
processes from left to right. The first regex that matches an existing
file is used as original file.

When used with e.g. "(.*)/(.{8})(.*)" as modifiedFileComponent and
"\\1/\\2.JPG;\\1/\\2.CR2;\\1/\\2.CRW" as originalFileComponent this
stacks all files with the same 8 characters onto each other.

This does not prevent the loading of multiple files but merely stacks
them on top of each other.


This addresses most of the comments on the old patch and actually
works better than my previous patch.

Comments?

Andi
