Milutin Kristofic c218df50e3 Reduce number of DOM Elements for Change Log
Gr-hovercard-account is shown only on hover. After fix, the app
creates all its DOM elements after hovering for the first time.
This saves 20 elements per account label, per 1 line in change log.

Gr-comment shows Save/Edit/Cancel actions only on drafts. After fix,
the app creates these actions only on drafts and not on all comments.
This saves 35 elements per comment.

Gr-message shows the Reply button only when expanded. After the fix
the app creates the button only after expanding for the first time.
This saves 20 elements per message.

When tested on /c/gerrit/+/251578 Change:
 - Show all entries was faster by 22% (1s -> 0.78s)
 - Expand all was faster by 47% (4.3s -> 2.3s)
 - Change pageload was faster by 3% (3.4s -> 3.3s)
