Components Page Next Button

[edit] Description

Enabled 'Next' button looks confusing if none of sections selected. Function disables Next button on the components page for this situation. Simple components structure in this sample (no groups), 4 sections - use your own section names in function instead og gXX. Another way is to make one section read only and checked.
