Missing Compatibility with new SBL-Feature "hide when prepopulated"

[twiro]

When I try to add a SBL+ Field to a section in a fresh Symhony-2.3.3-Install I get the following error:

Symphony Fatal Database Error: Unknown column 'hide_when_prepopulated' in 'field list'

Seems like SBL+ doesn't support the new "hide when prepopulated"-feature that was introduced in SBL 1.27:
symphonycms/selectbox_link_field#37

I ran into this issue just now and I added an extra column in the database table sym_fields_selectbox_link_plus called hide_when_prepopulated.

This seemed to somewhat resolve the issue, although I haven't investigated it further. Hopefully we can get an update soon :)
