[Feature] Better/more character info

[malouro]

Summary

The !character command could be improved a bit, and show some more information:

For example, it could be useful to have information on:

• Schedule (where to find the character & when)
• More information on liked gifts (instead of just loved)
• Heart events (put spoiler tags around these if needed)

Details

If the character info embed gets too cluttered, there could be an addition of parameters to get more specific information.

For example:

!char Abigail hated -> can show Abigail's hated gifts
!char Harvey quote -> gives you a random Harvey quote

This might be useful for character schedules, where input on the in-game date & weather could be necessary

#4 added gift information, inquiring about any available character info, and preliminary work for getting character schedule info
