Remove Task Scheduler, App Lifecycle, TCP UDP Sockets, App URI about html5-overview

[dret]

task scheduler: 1b84363
app: URL: da934ae
TCP/UDP: f8918bf
the lifecycle spec was never in the HTML5 list, i think, afaict, since it never made it to FPWD. i think these fixes resolve this issue, and if so, please close. thanks!

added lifecycle for completeness b14b2f9, but it now shows up as "other" since it is not an official W3C NOTE. maybe not quite what you were looking for, @sideshowbarker?

Well, I personally wouldn't include that spec, since it's not been updated in more than a year, doesn't seem to have any implementor support, and at this point has no home in any W3C WGs nor anywhere.

But I won't object to it being included if you want to. At least it's in scope as far as being intended for implementation in the Web runtime and the Web security model (as opposed to the other SysApp WG drafts, which were intended for a hypothetical off-Web runtime/security-model that never materialized).

Still I think that lifecycle spec has near-zero chance of ever getting implemented across UAs (or probably any UAs), and so near-zero chance of every becoming part of the Web platform.

Closing this since the specs in question have now been removed from the overview and I opened #27 about dropping Application Lifecycle and Events.
