Added the 'a' option to app dial and modified app_dial to set the answertime when the called channel answers.

This change causes answertime to be correct even if the called channel hangs up during an announcement triggered by the A() option.

  * Added functionality to the app_dial F() option to continue with execution
    at the current location when no parameters are provided.
+ * Added the 'a' option to app_dial to answer the calling channel before any
+   announcements or macros are executed.
+ * Modified app_dial to set answertime when the called channel answers even if
+   the called channel hangs up during playback of an announcement.
  * Added c() option to app_chanspy. This option allows custom DTMF to be set
    to cycle through the next available channel.  By default this is still '*'.
  * Added x() option to app_chanspy.  This option allows DTMF to be set to
