Bug 29632: Don't sort cn-sort numerically

When defining our sort fields in we defined all as 'numeric'

For other string containing numbers this is likely correct, however,
for callnumbers it is not. e.g. E45 should sort before E7

This patch adds a new 'callnumber' type and deifnes this for cn-sort and
adds to the field maping a sort without numeric set

To test:
0 - Be using ES with Koha
1 - On records with single item, add callnumbers:
    VA65 E7 R63 1984
    VA65 E7 T35 1990
    VA65 E45 R67 1985
2 - Add public note 'shrimp' or something to make them easily searchable as a
group
3 - Search for 'shrimp', sort by callnumber
4 - Note E45 comes last, it should come first
5 - Apply patch
6 - Reset ES mappings
7 - Reindex ES
8 - Repeat search
9 - Sorting should be correct when set to callnumber
