Remove md5 sums from the index (fixes: #336)
Add subdir support to gradle
Only do an update if the vercode changes

(mainly to work around a recently introduced issue where the name

Fix sha256 sums not appearing in the index
Print progress messages as a build goes thru various stages.

Without this, we get bunch of messages at the start of build, which
end with "Applying patch", and then all the things hangs for several
minutes (or more, in case of network problems, etc). So, consistently
keep user aware od what's happening. Note that --verbose switch affects
deatiledness and amount of output (in particular, if it's given, "build"
command output goes to console instead of log).
