View block doesn't show transaction ids in the tx field #135

It seems to be confusing some users that the "tx" key is empty when viewing block info. We need to show transaction id's somehow.

The reason it's not done already is that there could be many tx's, hundreds or maybe more, and if we naively render ever single one and a user looks at a block with many tx's, the UI will look funky and might be unusable (such as if the buttons in the modal window are off the visible screen).

I think what we need is something simple if there are less than 5 or 10 transactions (which is probably 99% of blocks) and then a scrollable list if there are many tx's.

It would be awesome if it was possible to right click on transaction ids (when they are rendered) and view that transactions specific details, which ties into #136

We now have basic "view the txids in a block" functionality, but it needs to be improved.

Make txid text selectable so a user can at least copy+paste txids somewhere
Make txid a scrollable list with one txid per cell, so a user can right click on a txid and get menu options

All items are now selectable. There is no right-click menu but the user can CTRL-C what is selected and paste it somewhere.

We now have a selectable txid and one txid per cell. There is no scrolling (if there is a huge amount of tx's in the block, the popup window will be huge) and there is no right-click menu. Those can be improvements in a different issue. Closing this
