AjcTask: make version number arrays more generic

AjcTask: make version number arrays more generic

SOURCE_INPUTS, TARGET_INPUTS, COMPLIANCE_INPUTS are now populated in a
'for' loop in a static initialiser block. I.e., adding support for a new
Java version is now as simple as incrementing field JAVA_VERSION_MAX. In
case ECJ raises the minimum supporter compiler source/target version,
field JAVA_VERSION_MIN needs to be incremented. But that should happen
less frequently.

This was done to make the 'AspectJ_JDK_Update' tasks as easy and as
little error-prone as possible.
