Overdraw burritos

[chralp]

New feature to enable overdraw daily given burritos. Sometimes you maybe want to give more burritos then 5. But not increase the daily burrito cap and create a burrito inflation :) . The new idé is to set up av new form of cap ( overdraw cap ), where u can set it to maybe 5 and the overdraw burritos will be draw from the users own points.
Which means that a user can send ( in this case ) up to 10 burritos per day, but 5 of those will be drawn from the users own score.
