> JSON-RPC interface

For interfacing to MIDAS just from browser javascript, the user does not need to know anything about JSON-RPC, all the user-level mjsonrpc_xxx() functions provided by 
mhttpd.js work the same as the old ODBxxx() functions.

As usual, the functions are documented using Doxygen, so here there is no difference between old and new interfaces.

To generate the documentation, run "make dox" (doxygen and graphviz "dot" packages should be installed). (it will take some time to generate everything), then open 
html/index.html and navigate to "files" to "mhttpd.js" and you will see the list of all RPC funcrions (old functions are ODBxxx, new functions are mjsonrpc_xxx).

There was a possibility to implement the mjsonrpc javascript client interface as a javascript class, but older versions of doxygen seem to work incorrectly for such code making it 
impossible to document the code. So it remains implemented as traditional functions with a few globals, but the design an implementation are done with a view to convert the 
code to a javascript class some time in the future.

As ever, the examples/javascript1 experiment provides examples of using all available javascript functions supported by midas. (except for functions that are hard to example or 
hard to document).
