Add Page and Action tests related to reviews; some tests fail
Add Page and Action tests related to reviews; some tests fail

These three tests fail:
[error] x A page can
[error]   x have a body, with an edit, applied, and
[error]     x approved, automatically
[error]       'false' is not equal to 'true' (PageTest.scala:209)

[error]   x have a body, with an edit, applied, and
[error]     x approved, manually
[error]       'false' is not equal to 'true' (PageTest.scala:209)

[error]   x have a body, with an edit, applied, and
[error]     x rejected
[error]       'false' is not equal to 'true' (PageTest.scala:183)

I intend to fix them soon, by tweaking ViPo.
