State that DESCRIPTION is unaltered

This PR is a bit of banter which I am not sure you are going to merge, or maybe merge after you make me add a verbose flag, but we now also say what we are not doing. Compare to the display in #12:

edd@paul:~/git/tl(master)$ trox.r 
Checking CRAN compliance...
Parsing R files...
Found 11 documentation block(s).
Generating Rd files...
Generated 1 Rd file(s).
Generating NAMESPACE...
Updated NAMESPACE.
Left DESCRIPTION alone as one should.
Warning messages:
1: CRAN: Exported functions without examples: debug, info, warn, error, critical, set_level, \
   get_level, set_name, get_name, set_format 
2: Undocumented parameters in set_format: utc, show_date, show_thread_id, precision 
edd@paul:~/git/tl(master)$ 

I leave it to your expert judgement to see if this 'improves' things, and remain curious about what your silicon coding partner makes of it.

PS Maybe also s/Left/Leaving/ ?

Ok, and in a more useful manner we now have a 'silent' argument suppressing all this. The issue in #12 is still there though even if cran_check=FALSE:

edd@paul:~/git/tl(master)$ trox.r 
Warning message:
Undocumented parameters in set_format: utc, show_date, show_thread_id, precision
