Changing shortcut and item name of "Force Identify"

[humdinger]

My revision is hrev28069.

As I threatened at BeGeistert, here are some minor things for Alexandre. :)

There's an item "Identify" in Tracker's file menu and context menu. It sets the filetype of files that don't have one yet.

By holding down the command key (option key? No idea, it's AltGr to the right of the space key on my keymap), "Identify" also corrects a wrongly set filetype. At least it sets the filetype it's convinced is correct.

There are already a few items that change slightly when holding the SHIFT key (see e.g. Cut/Copy/Paste or Clean Up in the Window menu).

I propose to also use the SHIFT key as modifier for the identifying.

We should also reflect the slightly changed function in the item name. Generally, it's desirable to keep the first word "Identify" so not to confuse the user. I suggest: "Identify & Correct".

While i was looking at this, i couldn't find a test case where a "force identify" is needed. I slightly remember you had one, care to refresh me? :)

In fact, i don't think i ever had to click the "identify" menu item, when i right click on a file, it gets identified automatically, so i never have to select "identify".

BTW, i'm sure i'm missing something here, but what's preventing us to always identify without user intervention?

I finally remembered why there is a "force identify":

Assign "text/plain" to a PNG file and "Identiy" won't correct it back to PNG. "Force Identify" does.

Now, it can be argued that a) "Identify" is useless because as soon as you right click an unknown file, it's identified automatically. And b), how practical is the scenario with a wrongly set MIME type? Maybe after downloading files from misconfigured servers? I don't know.

The solution I'd prefer, if the feature for scenarion b) is needed at all, is to have another button "Auto-detect" in the FileType Add-On besides the "Select..." and "Same As...".

Thanks for looking into it!

Finally managed to implement that in hrev29940, sorry for the delay Humdinger ;) Had a few words with Axel and, as i said in the commit message, we will get rid of this 'issue' once identification gets automated.
