[Done v155b] admin css selector language-dependent

[torvista]

While investigating why the admin buttons were not aligned ONLY in spanish:


I found this surprise in the css:

img[alt="Cancel"], img[alt="Reset"]{
vertical-align: top;
}

which evidently will not work for non-english alt tags.

I changed it to this:

img[src*="button_cancel"], img[src*="button_reset"]{
vertical-align: top;
}
