WebNetCPU changeset:
1) feature-test added for a Blob support (mainly for older, unsupported browsers).
2) more code simplification w.r.t. not adding logit models to the 'to be periodically animated' array.
3) more tunable shaking and value-interpolation objects (and subsequent, minor, retuning of the animations).
4) other minor things like not reparsing int of the arguments which are already expected to be ints.
