win: Allow for selection specific image

Browse Source 
This is useful if the install.wim contains multiple Windows versions
(e.g., Home, Pro, ..), because the autounattend file will always select
index 1. With this mechanism, a variant different from the first one can
be automatically selected. imageSelection can be either an index (1-N)
or the image name wiminfo can list all images contained in a given WIM
file.

The default case is index 1, which has the same effect as before, with
the possibility of having a slightly smaller install.wim file because
all unwanted variants are discarded.
