IL: Minor point concerns

[Markkos1992]

It looks like we can easily make 57B just plain 57 now.  Looking at the Github files, 57 (or 57(94) in the case of I-90) is not being used in either file.

MusCamDr should be 18thDr.

All of these also affect IL 110.

1.  A point should be added at 24A.
2.  24 should be 24B.
3.  30 should be I-90/94.  I could not find an Exit 30 on any GSV image (past or present).

I-88:  54 needs to be recentered.

IL 56:  The labels along the I-88 concurrency need to be replaced with I-88(113), I-88(114), and I-88(117).  Of course, I did not even realize this concurrency was truly a thing until reviewing my notes afterwards.  Honestly, while driving I-88 WB, I thought that the references to IL 56 EB and WB were for different exits and had nothing to do with a concurrency.

US 6: 
1.   KimRd should be KimRd_E. 
2.   QuaCitAir should be QuadCityAir.

IL 84:  I think ColRd_W should be just ColRd.

IL 5:
1.    Should DenRd be HubRd?
2.   Should MilPkwy be RIMilPkwy?

IL 92: 
1.   Should DenRd be HubRd?
2.   14thSt should be recentered between the one-way sections.

US 67:
1.   Should 1stAve be AirRd (Airport Rd)?
2.   I recommend adding a point at 31st Ave due to its direct connection to IL 92.  7th Ave is already close to 11thSt.
3.   11thSt should be 11thSt_N. 
4.   15thSt should be 15thSt_S.

Consolidated thread.

Since you consolidated threads here Highway63, I'll just quickly throw in a few exit number issues I saw on I-94 that need to be addressed.

il.i094:
22 -> 24
25 -> 25A
26 -> 25B

And don't know if you want to tweak this one or not, but you might be able to get away with this change on I-294 if you want to, but I'd understand if you didn't want to do the tweak:

il.i294:
I-94_W -> 52

Also, one exit on I-90 that needs to be addressed that I spotted too.

il.i090:
100 -> recenter (this one is badly way off from the overpass, might even be able to justify adding a shaping point in the 'old' 100 location too)

All of these also affect IL 110.

1.  A point should be added at 24A.
2.  24 should be 24B.
3.  30 should be I-90/94.  I could not find an Exit 30 on any GSV image (past or present).

I am not sure how the I-290/IL 110 concurrency broke.  (For IL 110,  I-190(24B) needs to be I-290(24B).)

This point is intentionally centered at where the half-interchange ramps join/leave the mainline to create some separation between points.

The IL 110 point break is related to the addition of the new exit on I-290. Had a slightly different coordinate.
