Reviewed Pagination and Pager.
For Pagination:
- use mixin ".pagination-size" also for base size
- make pagination variables naming scheme conform, deprecated old ones
- make pagination more customizable by supporting variables for color, bg and border in all states (default, hover, active, disabled)
- harmonize handling for inner 'a' and 'span' tags
For Pager:
- make pager more customizable by using variables of pagination for color, bg and border in all states (default, hover, active, disabled)
- deprecated variable '@pager-disabled-color', because it is now a 'duplicate' of a pagination variable '@pagination-disabled-color'
- harmonize handling for inner 'a' and 'span' tags
This is a replacement of pull request #11684
