include field for author name and utilize in taxonomic validation

[GoogleCodeExporter]

Some plant synonyms cannot be resolved without including author name(s). 

Here are two examples with palms:

1. 
Accepted: Dypsis humbertii H.Perrier
Verbatim: Dypsis zahamenae J.Dransf.

Accepted: Dypsis henrici J.Dransf., Beentje & Govaerts  
Verbatim: Dypsis humbertii (Jum.) Beentjei & J.Dransf. 

2. 
Accepted: Dypsis linearis Jum
Verbatim: Dypsis anovensis J.Dransf.

Accepted: Dypsis procumbens (Jum. & H.Perrier) J.Dransf., Beentje & Govaerts    

Verbatim: Dypsis linearis (Becc.) Beentje & J.Dransf.

Under the current system, it's not clear what happens to a record uploaded as 
Dypsis linearis. Is it accepted as Dypsis linearis or Dypsis procumbens? This 
can only be resolved reliably by including author. 

Requires at least two enhancements: 
A. Expand occurrence table to include field for author name (if it doesn't 
exist already)
B. Utilize author name in taxonomic validation

A few thoughts: 
- Different name spellings should not be treated as separate species 
- Does this apply to plants only? 
- Is it like subspecies, where we include if it exists, and ignore otherwise?
- This will also have to be formally incorporated into the development of 
taxonomic authorities (for plants only?)

critical for plants. The solution needs to be defined, but comes down to a test 
of ambiguity - if ambiguous we need the author name to validate. Some burden on 
user to supply correct author name (and correct abbreviations, we will not try 
to guess correct author from poorly abbreviated names)
Overall, if possible, best to provide a solution to this in validation logic, 
not by making the authority more complex
