Removing trailing whitespaces from idea asset
Remove deprecated adt eclipse assets
Fix medium tests by shipping new upstream sdk html files and settings
Remove trailing whitespaces from android's sdk index.html
Ensure fetch android studio download link using a secure connection

Medium tests were failing because we used the http one. Using the https one is
more secure as then the download is doing over http (but the checksum, fetched
from the first page is checked)
