Options dialog improved

The options dialog have some problems but they were addressed like:
- support of multiple sections. This is done using a global factory system. Before this you had to complete the list of pages and populate and would make harder.
- the search work contextually so it search the content of options pages without any code necessarily from dialog creators. This means that if you will create an option dialogs using your Windows.Forms dialog and all content is indexed. This will mean if the options dialogs will increase in count, the search will be relevant and simplify the usage of this dialog
- the toolbar checkboxes order were in wrong order
