Add Warning About Poll Requirements To Poll Creation Menu

[RoboticMind]

Seeing as there have been a fair number of invalid polls being made, I think it might be worth adding something before the poll creation menu to remind/inform people about the poll requirements. Hopefully this could help cut down on the number of invalid polls.

Not sure if this would be best done by linking somewhere or listing out the requirements as they currently are. The issue with linking somewhere is that 1) people might be more likely not to click on it and just ignore it 2) figuring out what place to host it. The issues with listing it out is that it may change after voting so it might not always be accurate for people using older versions of the wallet.

If we want to link to a page, we can link to voting wiki page which lays out the requirements. If we want to jump straight to the requirements section, can use an anchor tag like this: https://gridcoin.us/wiki/voting.html#poll-requirements

I think with the link to the voting wiki page in the wallet and other detailed instructions, this can be closed
