Users should be able to check how many tickets / entries they have entered into the active giveaway. Currently only the streamer can check, and has to do it frequently when many people ask how many tickets they have.
A simple command such as !tickets to check how many they have would be great. In addition, perhaps it could show how many they have left to obtain before they hit the maximum number of entries.
For example @user, you currently have 10 out of a total of 50 entries in the active giveaway.
