Squish Tests: Block functionality in Scripting

As a developer I would like to verify the following behaviour using Squish:

- Set up a block and go to the `Scripting` perspective.
- Verify that running `g.cget("")` returns the correct values.
- Verify that running `g.cset("", )` sets the correct value.
- Verify that running `g.cshow("")` returns the correct string information.
- Verify that running `cget` on a disconnected block returns the correct values.
- Verify that running `cshow` on a disconnected block returns the correct string information.

#### Additional info:
Can use the SIMPLE IOC for the various blocks.
