Improve Current directory structure

In the documentation, the $Run and it's $Input commands are capitalized. Is that necessary? - Other commands don't have capitalized first letters.

At least in the documentation, the csproblem command has a double $ prefix. None of the other commands have a $$ prefix. I'm guessing it's a typo.

The $csupcoming and $cspresent command outputs the dates and times of the events, which also include seconds. Seconds seem unnecessary.

Example of how the run command could work:

$run
```python
a = input('Enter a number: ')
b = input('Enter a number: ')
x = float(a) + float(b)
print(x)
```
$input
```
3
5
```

1. Multiple inputs could be given
2. A single command for C and Python is easier to remember for users
3. The code would be formatted and the syntax can be taken from the code block
4. $input can be used within the code
5. When users have a link in their code, discord will ignore it and not create a preview embed.
6. Syntax highlighting while typing the code
   
7. The $input part could actually be removed. The second code tag could always be considered as the input.
