Rename Service Explorer
[Android] Update min api version in templates
[MobileServices] Disable create after clearing subs

Disable create button after clearing subscription.
After anything but OK, show 'sign-in/import' message only if no
subscriptions, else reload services list.
Merge branch 'dev' of https://github.com/MSOpenTech/msopentech-tools-for-intellij into disable_mob_serv_no_subscription
Merge pull request #35 from leotilli/disable_mob_serv_no_subscription

Looks good to me...
