Add allow_warnings, fix abort_on_first

Allow-Warnings is finally available. (Closes #34)
  - Setting this option puts PySHACL into a non-standard operation mode, where Shapes marked with severity of sh:Warning or sh:Info will not cause result to be invalid.
  - Despite the name, it allows both sh:Info and sh:Warning.
  - Try it with `allow_warnings=True` on `validate()` or `-w` in the CLI tool.
Fixed Abort Mode. (Fixes #75)
  - This optional mode allows the validator to exit early, on the first time your data fails to validate against a Constraint.
  - Name changed from `abort_on_error` to `abort_on_first`
  - Try it out with `abort_on_first=True` on `validate()` or `--abort` in the CLI tool.

 ## [0.14.4] - 2021-05-26
 
 ## Added
 - Added an iterate_rules option, that causes SHACL Rules to run repeatedly until reaching a steady state. (Closes #76)
   - Works with SPARQLRules, TripleRules, and JSRules.
 - Variables {$this}, {$path}, and {$value} will be populated in the sh:message of a SPARQL Constraint. (Closes #30)
