'ant install' must know the debug apk filename so newer naming scheme breaks
on older rule files (1.5 and earlier).
The fix is to check for the presence of the property naming the debug,
signed, unaligned package. If the property is present, then we use
the new naming scheme ({base}[-{config}]-debug-unaligned.apk), else we use
the old one ({base}-[-{config}]-debug.apk).
Also merge the install/reinstall targets, since 'adb install -r <file>'
works even if the apk was not yet installed.

Resource filters are used when generating additional APK containing only
specific resources.
The previous UI allowed for any type of filters, but we are moving to a
simpler way with fixed filters.
The first one is the density. Selecting the filter will generate 4 APKs per
application: default (all resources), hdpi (only hdpi/nodpi and default
resources), mdpi, ldpi.
