Logic building blocks

Current implementation of logic templates in build tab doesn't allow random logic and to create all in one build config.

I would like to see logic section in building blocks.
Logic section will increase diversification a lot.

1. It should have some predefined logic
2. Each template should have weight
3. There should be a random template to generate random logic

Predefined logic examples:
a. Default long priority
if LongEntrySignal
long open
if (ShortEntrySignal
   and Not LongEntrySignal)
short open
if ((LongExitSignal
   and Not LongEntrySignal)
long exit
if ((ShortExitSignal
   and Not ShortEntrySignal)
short exit
----
b. Default short priority
if LongEntrySignal
   and Not ShortEntrySignal
long open
if ShortEntrySignal
short open
if LongExitSignal
   and Not LongEntrySignal
long exit
if ShortExitSignal
   and Not ShortEntrySignal
short exit
----
c. Strict
if LongEntrySignal
   and Not ShortEntrySignal
   and Not LongExitSignal
long open
if ShortEntrySignal
   and Not LongEntrySignal
   and Not ShortExitSignal
short open
if LongExitSignal
long exit
if ShortExitSignal
short exit
