bio.tools ID to be a subset of xs:NCName (fixes #79)

[matuskalas]

Slighly limited the xs:pattern of the bio.tools ID, so that it is always an xs:NCName. This is required for usage in RDF/XML (Linked Data).

This fixes the last open point (the 3rd) of #79 (comment).

Also slightly clarified the xs:documentation of biotoolsUrlType and urlType, and moved the detailed xs:documentation from otherID/type and biotoolsID to biotoolsIdType accordingly (updated version of

biotoolsSchema/biotools_dev.xsd

Line 212 in 753c572

<xs:documentation>bio.tools toolIDs are a URL-safe derivative of (often identical to) the tool name. Unreserved characters (uppercase and lowercase letters, decimal digits, hyphen, period, underscore, and tilde) are allowed. All other characters including reserved characters and other characters deemed unsafe are not allowed. Spaces can be preserved as underscore ("_").</xs:documentation>

and

biotoolsSchema/biotools_dev.xsd

Line 136 in 753c572

<xs:documentation>The ID is a URL-safe derivative of (often identical to) the tool name restricted to 12 characters maximum. Unreserved characters (uppercase and lowercase letters, decimal digits, hyphen, period, underscore, and tilde) are allowed. All other characters including reserved characters and other characters deemed unsafe are not allowed. Spaces can be preserved as underscore ("_").</xs:documentation>

).

N.B.: As much as could search through the bio.tools GUI, it seems like all the assigned bio.tools IDs anyway satisfy this new pattern. But must be double-checked, and if needed fixed.

This is excellent, thanks a million! Just to be clear, am I right that biotools toolIDs must now start with an underscore, a letter or a number?

[matuskalas]

To clarify: bio.tools tool ID must now start with an underscore or an English letter. Not a number! This is requirement for being a valid NCName, usable in RDF/XML (and perhaps also other Linked Data formats).

@joncison @matuskalas
Well, I don't know what to say about that, I don't think it's realistic for bio.tools, many tools start with a number (a good example are tools that do something with 3D and thus the id starts with 3D...)
I could add an underscore to those ids that start with a number, but this would mean breaking the existing ids and also not representing the tool name as it is (personally I think they would look ugly)
