Thanks a lot to plc5_250 on IRC for testing.

We need to reimplement an on-the-fly option to record streams.
I know this commit is crappy...

Thanks a lot to ipkiss for providing the bisect builds and geal for his help.

One side effect is that the snapshot is now taken using the picture that
will be displayed (chroma and resize filter applied).

It will allow to have different procedures for osd subpicture and subtitle
subpicture.

( At best, a = b++ is not atomic)

This will slow a few complaints from many people.

Pretty please, remember to delete the file name in POTFILE.in when you delete them from git

This reverts commit 65052fef.
It's already taken care of in the for loop just before

Ogg can be now: ogx, ogv, oga but we have to keep ogg and ogm for backward compatibility.

F1 and Ctrl+F1.

I don't know what to do for F1 tough.

1) Every Human Interface Guideline on Unix/Linux/Windows reserves alt key for menu and button accessibility... Try to NOT use those...
Moreover, you have NO idea how the translators are going to translate your accelerators...

On the other hand, with this long list of keys it was become more than difficult... I'll document on the wiki.

2) Use keys next-to-each-other like-a-cross for cropping

Those keys are making a cross in most layouts ( on the contrary to the previous ones).

3) At the same time, use easier snapshot key. (shift+s is easier than Ctrl+alt+s)

4) Comment previous changes and remove whitespace.

Nota Bene:
I have no idea on how are the default on the mac and if the are conflicts there too, so I won't make changes there.
