r7002: added support for getting at loadparm config parameters via lpGet() in esp scripts

lpGet takes 4 forms
    v = lpGet("type:parm");             gets a parametric variable
    v = lpGet("share", "type:parm");    gets a parametric variable on a share
    v = lpGet("parm");                  gets a global variable
    v = lpGet("share", "parm");         gets a share variable

in all cases a ejs object of the appropriate type for the variable is returned.

This commit also adds the function typeof() which returns the type of an object
(This used to be commit 5537a0d38d4805cbc2dad0d6f76db15173b1fd60)
