"OR" operator

[Igreh]

It will be very useful to have simple "OR" operator.
Ex: check whether value is string or null @string@||@null@ or @string@.or(@null@)
Is there any way to implement it?

And yes, I know I can extend expression language and add my own functions but native implementation is more descriptive, imho

@string@||@null@ would be awesome, just need to find some time to implement it :P

@norzechowicz please look at #74

@partikus I have seen that (awesome work!) but I would like first to solve #71. I'm not sure if #74 wont complicate #71 even more.
