This is instead of hard-coding a call to SetDefaultWindowsBindings().

@andschwa - you're right, it looks like the call to Clear is no longer needed. |

Per #1085, there was confusing over keybindings on Linux / OS X. Since we use PSReadLine, it is up to the user to choose a preferred editing mode, and PSReadLine reasonably defaulted to Windows. However, this leads to a subpar experience on non-Windows platforms, where almost everything respects Emacs keybindings (especially shells).
This fixes PSReadLine so that the key bindings are set based on the default edit mode, and sets the default edit mode to Emacs when
LINUXis defined. Pester tests are included.I do, however, have an open question for @lzybkr about the need to
_chordDispatchTable.Clear()when changing key bindings. Each ofSetDefaultWindowsBindings(),SetDefaultEmacsBindings()andSetDefaultVimBindings()bind_chordDispatchTableto a new dictionary, thus overwriting it. Is it actually necessary then to clear the previous value?
