Avoid table in single block explorer

[helins]

Exploring a single block should not be formatted as a table. That would improve the mobile experience but also the desktop one. On my desktop I get an X scrollbar:

No concrete idea about the alternative yet, we can brainstorm it. Overall, it should be a vertical layout of key-values pairs instead of a horizontal one.

@helins, we are using a table because a block has n transactions, although most of the time, we see only one.

Any thoughts on this @mikera ?

2 ideas:

• Alter the text to say something like "[n] Transaction(s) in this Block"?
• If you are showing the table for a single block, remove the "Block" column from the table (it is redundant and confusing in this case)

At least now it doesn't show an X scrollbar on a larger screen :)
