Fix fuzzy detection to prevent misdetected mine names

At times when myself or my server administrators are resetting a mine, it will pick up the wrong name for the mine instead of returning a "multiple result" error. We've taken to changing the mine names to completely separate three-digit numbers, but this is confusing to our staff team as we've had to write out a list of these new mine names (in correlation to the real mine names.)

A good way to fix this issue with fuzzy detection is to change
```java
if (mine.getName().toLowerCase().contains(in.toLowerCase())) {
    matches.add(mine);
}
```
**to**
```java
if (mine.getName().toLowerCase().equals(in.toLowerCase())) {
    matches.add(mine);
}
```
