Structure page usability improvements

[luis100]

Descriptions should be placed next to column names.

“Description” of the content of the column is the most important information for the end user who has to comprehend the content of the database. There for “Description” should be placed next to column name.

“Type name”, “Original type name” and “Nullable” is information relevant for more advanced users.

Add explanation to the structure page of what user can see in this page.

Explain that this is a list of all the tables, their columns and foreign keys (relations to other tables)

“Name” for Foreign key should be renamed “Key name”

User confused name under Foreign key with name of a field
