Update travel sponsorship policy
There are a few problems with the current travel policy that we'd like to solve, including:
- It doesn't work well for people who cannot carry the cost of a trip until reimbursement after the trip is over.
- The wording is very stern and seems to demand that people justify themselves.
- Some policies are not written down (e.g. that we sponsor travel to and from airport)
- Verifying costs takes a lot of effort from the travel committee
Propose a new policy that has a friendlier tone, allows for a wider range of financial circumstances, is complete, and asks applicants to send in screenshots of their flight searches like the Foundation travel policy.
