"copyable" component allows any elements to be wrapped to include:
- a tool tip that changes/debounces its label when clicked.
- a customizable copyable value.
Fixes#1539
Fixes#1439.
When reorganizing fiat-value component to not use global state, had missed its necessary `currentCurrency` parameter.
This now passes it in wherever it's used.
- Now striping hex prefixed gas values, which may have been causing mis-estimation.
- Unified calculation logic to be entirely functional.
- Greatly simplified how the pending-tx form keeps updated form state.
Still needs a commit from @kumavis to ensure the background passes in a txMeta.txParams.gasPrice value.
Sorry apparently the gas fixes weren't in the last commit, but are in this one.
As reported in previous commit, fixes a bug where initial estimate is not derived from the network.
Also fixes a bug where clicking "reset" does not clear our custom validation warnings.
These were only separated originally so we could make the notification-based TX approval work, which provided its own buttons.
This two templates are logically highly coupled, and keeping them working while separate has been difficult at times, and has even required resorting to dubious practices, like using React's `refs` pattern.
This combines them into one fairly large component, but I think it's ok, we can still break this up into components, just not the separation that it had previously.
