When updating a previous installation, old eSpeak voices are now removed.

Before copying in the new files, everything in the espeak-data\voices directory is removed except for variants.
Otherwise, multiple copies of voices and other files can be left around when they've been moved in eSpeak. In particular, the recent reorganisation of espeak-data\voices means that there are a lot of duplicates.
Fixes #3181.
Fix #3151 (browse mode does not work in IE 10 on www.gmail.com login page). When IE 10 is in standards mode document.getElementsByName nor getElementById will return a node given its MS unique ID. However, document.all.item(uniqueID) does work. So only in this special case (for now) if getElementsByName returns None (only happens in IE 10 standards mode) then try document.all.item(uniqueID), but catch *all* exceptions around that line to make sure there are no surprizes introduced by this very specific fix. In long-term it would be good to move code to just use all.item all the time, but this of course is untested.
