Should create new sub-tabs for blocks based on function (power, transport, defense, etc)

[Redoneter593]

Due to how many more new blocks there are as of 7.0 and in total, it takes a while to find blocks on the wiki by scrolling and should really have sub tabs for specific block purposes so. (The same goes for Modding Classes) Example:

blocks>

    power>
    transport>
    production>
    defense>
    unit creation>
