In-place filt!, allow passing initial filter state

This redefines `filt` as `filt!` with a few modifications to perform its
filtering in-place. `filt` is defined as a simple wrapper, copying the vectors
that `filt!` modifies.

Further, both methods now allow an optional argument for the initial filter
state vector. This vector is modified in-place in `filt!`.
Be smarter about the initial filter state

Compute an initial state for filt such that its response to a step function is
steady state.
improve windows readme. ref #6795
WINDOWS: fix #6795. always read the terminal in unicode mode, and set the default codepage to Latin-1 (so that we can be certain that C programs can read/write ASCII data to the terminal successfully)
WINDOWS: add Julia Studio mention, break up some of the paragraphs for easier future maintainability, and other minor textual tweaks

Recreate packagelist.rst in an attempt to flush readthedocs cached copy.

This link still works: http://docs.julialang.org/en/latest/packages/packagelist/, but it shouldn't.
Now that ReadTheDocs has updated its cache, it might be safe to delete the file again.
