Tablesorter/Improved parsers

In December 2015 I (MatthiasDD) started to solve task T29745, References in column affect sorting and T46818 jquery.tablesorter should sort plain year digits as date. Later I take care some other Tasks that be connected with the right detection of parser.

Now I suggest to change the parser detection of sortable tables for all types as follows: So "about 1870 " would detected as year without use of Templates.
 * 1) References  removed from sort value.
 * 2) Text before sort value is allowed.
 * 3) Text after sort value is allowed.
 * 4) A plain number 1-4 digit can detected as number, date, or isoDate depend from other collumn content.

Some aditional improvements in parser detection are described below for each parser.

Test script
For testing without change the actual tablesorter.js you can add in your Custom JavaScript: After page loading are used the current parsers. Right-click at the table header activate the new suggested parsers that described here. It change the table also in my diagnosis mode: Show all sort values in that row in a message box, colors the background depend from detected parser for this cell and write title tags for each cell with detected parser (in brackets) and used parser (second line).

IPAddress
add support for IP/CIDR format, (solve T36475)

currency
Because Text before and after sort value is allowed. it's now done by parser. All other currency chars or text are possible. This parser can be deleted.

url
Has not worked since 2011-04-14 because the RegExp was. The $ means the input must end with ://, this is never the end of a url. I have changed this, but i would say: This parser can be deleted. See T47161 Kill all non-trivial parsers in $.tablesorter

isoDate
set in header means that the parser is defined with.
 * Time without Z was parsed as local time, that was false and is now UTC time.
 * Years 70...99 solved.
 * short forms are possible: JJJJ, JJJJ-MM, and only with  : JJJJMM, JJJMMTT

usLongDate
Need we this parser really? In my opinion this parser should removed later.

date
Olny year (1-4 digits) can detected as date. At detection of Parser for column this is put away as empty cell, if then 5 other cells found with date or  is written in table header, parser date is used.
 * RegExp inside '[]' (Ecma ClassAtomNoDash): only SourceCharacters \ or ] or - must be escaped.
 * A non breaking space is allowed as (single or aditional) dateSeparator (\xa0)
 * For written Month name (m) folowing forms are possible: dm dmy m md my mdy

time
Extended to format  ("932:20" was sorted in Firefox40 as 947968500000, in InternetExplorer8 as 0) see  TOI (Time On Ice)

number
set in header means that the parser is defined with.
 * digitTransformTable is used for standard and scientific format.
 * Text before number can have every character except -,+,−,digit (solve T65055)
 * Numbers can contain spaces  and '
 * Add infinity as [+-−]∞
 * Scientific notation is possible, a number must stay before [·×⋅]10^? see fa:%D9%86%D9%85%D8%A7%D8%AF_%D8%B9%D9%84%D9%85%DB%8C Persian: Scientific notation
 * Empty cells will be sort at end, with Number.MAX_VALUE (only ∞ is larger)
 * Cells with text will be sort after number 10000 (solve T123364)
