Fix syntax error in reset_simulator AppleScript

Adds a missing "then" at the end of an if statement.  You'd think
this would cause a consistent error whenever we tried to use the
script, but AppleScript tries to be "forgiving."
Change encoding of ellipses character in reset_simulator script

The AppleScript editor really seems to want this ellipsis character
to be encoded differently than we had it, so I'm going to let the
editor have its way in case this reflects an undocumented requirement
of osascript.
Initial release
Tap on the view backing an SLTextField before editing under most circumstances

Causes Subliminal to tap views backing SLTextField elements before
trying to set the text on those elements *unless* the backing view
is a UITextField and is already editing at the time that the setText
method is called.
Set text by typing on the keyboard instead of using JS setValue (resolves #2)

Causes text to be set on SLTextFields (and SLSearchFields and
SLWebTextFields) by actually typing on the on-screen keyboard
instead of using the setValue JavaScript function.  This is
closer to how a real user would set the text for these fields
so the new setText methods will yield more honest testing.

Note that the automatic wait for [SLKeyboard keyboard] to become
valid serves the same purpose as the old "waitUntilTappable"
calls---it causes a delay until the text field is ready to
handle editing actions.  So there's no need to wrap the editing
actions in waitUntilTappable anymore.
