Broadcast an intent to mediascanner after executing screencap

PS2: Fix for spaces in file names

After doing screencap /sdcard/test.png in shell the screenshot is captured
but the gallery is not updated.
So we should broadcast the intent android.intent.action.MEDIA_SCANNER_SCAN_FILE
for the image to show up in gallery.
