Add 'show' option to lxpanelctl.

[mozbugbox]

Fix issue #37

An improvement will be:
keep lxpanel showing while Win key is pressed, and hide on Windows key release.

Maybe lxqt-panel is the future. So I have a similar feature request there:
lxqt/lxqt-panel#1725

using xkeymap to achieve the same goal need another command“lxpanel hide”

Working fine here on Gentoo

using xkeymap to achieve the same goal need another command“lxpanel hide”

Couldn't find xkeymap,
Applied commandxbindkeysinstead after adding
"lxpanelctl show"
Super_L
to file~/.xbindkeysrc
which binds "Window key" here.

I would rather see a lxpanelctl "toggle" option that can be mapped to a key in order to show the lxpanel if it is currently visible and hides it if it is not.
