VID actors syntax errors are not caught

[hiiamboris]

Describe the bug

I believe it took @luce80 quite an effort to reduce unexpected VID behavior to this little snippet:

system/view/VID/styles/my-style: [
	template: [
		type: 'base
		actors: [
			1 + 1
			ON-CREATE: func [face][]
		]
	]
]
view [my-style on-time []]

Which when run outputs:

*** Script Error: ON-CREATE: needs a value
*** Where: ON-CREATE
*** Near : ON-CREATE:
*** Stack: view layout fetch-options context 

Assumption source:

red/modules/view/VID.red

Lines 482 to 484 in 5521b51

	foreach [name f s b] face/actors [
	unless find actors name [repend actors [name f s b]]
	]

Root issue: red/REP#132

Expected behavior

Either no assumptions on object source code, or explicit declaration of the format and a runtime check with helpful error message.
