At least if necessary (added new boolean flag to the constructor of
LargeResponseHandler for that). While at it also rename UrlForwardHandler
to UrlProxyHandler (it does not forward, it proxies) and make it aware of
ETag and Expires headers.
Bit of a debate with some gcode purists. RepRapPro demands an S
parameter. Adding S255 should be backward compatible with the firmwares
that recognize M106 as full on. As with other issues, it'd be nice to
have something more to go on here than the reprap wiki and firmware
source code.
ETag values returned with download responses were cached internally within
the LargeResponseHandler class, with the file's path as key. That let to
problems once the content changed and hence the ETag value actually
becoming invalid. Since the path however stayed the same, the same ETag
value for the modified file was assumed and a 304 Not Modified response
was generated.
This patch changes the behaviour of LargeResponseHandler to use
the last modified date of the file as the ETag value and alternatively allowing
an etag generator function to be provided as constructor parameter as well
to use for calculating (or disabling) the ETag header dependant on the
situation.
Needs to be calculated differently for time based and z-triggered. Capture interval
was not taken properly into account.

Capturing is now queue based, rendering will not start until all images have been captured,
and timed postroll does not depend on system time anymore.
Also refactored some of the names to be python naming compliant while at it.

This will directly offer a "Restart Now" button on the "a restart is required" notification
for plugins which cannot be directly enabled/disabled without a restart, but only if
the restart command is configured on the server.
On click a confirmation dialog will be shown.
PNotify always merges the default buttons and the ones provided. Just settings the default
to containing no buttons was no option since plugins might already depend on the so far
obligatory Cancel button being present. The helper allows to create one buttoned
notifications without touching the defaults.
In case the user site packages are not yet part of the used
working set OR the sys path and ENABLE_USER_SITE is true, the
manager will now make sure that the folder is searched for plugins
as well upon plugin reload.
This is necessary since Python will not automatically include the
user site directory upon firing up the program in case there's
nothing installed to it/it doesn't exist. If a plugin is installed
during run time with --user that will lead to it not being found,
which is undesirable. Hence run time manipulation of sys.path and
the workingset becomes necessary.
Managable currently pretty much only means "uninstallable".
Plugins are managable if their installation location is writable
and - if they are installed from an entry point and OctoPrint is
running in a virtual environment - within the bounds of the virtual
environment (because otherwise pip will not allow to uninstall).
