I added json-rpc requests for ODB /Script and /CustomScript (the first one shows up on the status page in the left hand side menu, the
second one is "hidden", intended for use by custom pages).

For us it would be a handy feature if history data could be requested directly
from a custom page (time range or run based intervals) . Here I am not talking
about history plots but I am talking about recorded time series data. This way

MIDAS does not seem to be consistent (or at least convenient) with how it
handles booleans in AJAX functions.

I am currently testing the new history system on the mhttpd side and stumbled over the following issue: typically our user open a lot of midas web-page
tabs and keep them open. With the current version this leads after a night typically to a state where the browser is busy with itself and not reacting
anymore.

Hi, Stefan - I did not look at your code, if all midas tabs are inactive, will the alarm sound still play?

Nope. All updates are done in mhhtpd_refresh(), and I changed it such that nothing is updated if hidden.
