Added source command to easter. This is the interactive equivalent of the -file option
Changed history to log a -file <file> as a "source <file>" into the history file
Changed prompt to
"easter>"
Documented easter on the wiki
Added rudimentary set/get commands to add things to the global $_optis hash. This allows the interactive user to set options like activecalls or displaylevel interactively for the during of the easter run. Note, there is no checking to insure the option if valid (i.e. set foo=bar is perfectly acceptable even though there is no "foo" option) nor is proper checking of balancing/mismatching of quotes (e.g. The results of set foo = "unbalanced or mismatched quotes' are undefined).
