Hotfix levelbuilder - API abilities

…[test all]

When generating code directly from XML, we use a helper that initializes
a new readonly blockspace, populates it with blocks, and generates code
from there. We would formerly accomplish this by populating the user's
working blockspace with the blocks, generating the code, and then
replacing the user's original blockspace, but this had some problems.

Unfortunately, the code generator, when scanning the code for variables
whose declaration it wants to pull up into the top of the block, only
considers the blocks in the main block space when looking for those
variables. This can lead to problems, as with [course 4, stage 18][1]

The simple fix is to have the generator directly scan for variables in
the blocks that it's using.
