incompatible sizes of some icons (compared to fontawesome 4.7.0)
Comparing to fontawesome 4.7 I find e.g. that 
.fa-user ([&#xf007])  is narrower than the forkawesome (1.2.0) version. I could correct this by adding this style 
```
.fa-user:before {
    content: "\f007";
    width: 23.7px;
    display: inline-block;
}
``` 
while the current version appears to be more like having an intrinsic width of
```
width: 20px;
```
For .fa-search-plus ([&#x\f00e]) I find a vertical off of being a two pixels higher than its "original" fontawesome counterpart. (font-size 30px, for font-size 52px the offset is 3px)
 
So, my questions would be:   
Should / could this be fixed?  
Did others notice similar discrepancies?
