Add referral links

[r4rdsn]

User is considered invited if they had gone through the referral link of another user and used escrow during 90 days after that.

Referral links can be implemented using deep linking of Telegram bots, this way bot can get the code linked to the referrer seamlessly when referral presses "START" button in the referral link, which in this case is bot's link with the start parameter set to that code (e. g. t.me/tellerbot?start=XXXX).

There are three categories of referral service's users:

1. User who invited others.
2. Users who were invited by the first category's user (first level).
3. Users who were invited by the second category's users (second level).

The number of invited users bring bonuses to the first category's user in the following way:

Category	1	5	10	50	100	500	1000	5000	10000	50000	100000	500000	1000000
1	1%	1%	2%	2%	5%	5%	10%	10%	20%	20%	40%	40%	40%
2	0%	1%	1%	2%	2%	4%	4%	8%	8%	16%	16%	30%	30%
3	0%	0%	0%	0%	1%	1%	2%	2%	4%	4%	8%	8%	20%

Header of this table describe levels - the number of invited users. Percents in cells describe bonuses - cashback ratio or discount from fee paid by the corresponding category's users for using escrow.

Code for the referral service should allow to change levels, each of the bonuses, the type of bonus (cashback or discount), cashback multiplier when giving away tokens (x2, x3 and so on).

To defend from cheating, escrow exchanges should be between different Telegram accounts and different blockchain addresses.

Only escrow exchanges with paid fee are taken into account in the referral system. If invited user didn't use escrow during 90 days after going through the referral link, they also aren't taken into account until they use it.

The statistics should look something like that:

Invited users: 10763
Invited users who used escrow during the last 90 days: 8302
Users invited by your referrals: 326789
Users invited by your referrals who used escrow during the last 90 days: 80012
Your overall status: 8302+(80012/100)=9102
You get a 10% cashback from your own fees
You get a 8% from fees of your referrals (first level)
You get a 2% from fees of referrals of your referrals (second level)
