Replacer #1158 (PatternRemover enhancement) and Second Typo #1645 (ABC Step Multiply)

PatternRemover has been enhanced to support 'replace with' and %macro% expansion by introducing 'sed' syntax to the preferences/UGS/Contoller Options.

'sed' syntax is "s/regex to match/replacement text". The code splits the regexpr string passed in (as defined by the user in the Controller Options screen) by "/" and acts according to how many sub-strings are found.

If 1 (and default), ie: no "/", treat this as a simple regex to find a match and replace with "" if found in the gcode.
If 2 then a half-sed syntax was used but the replacement is not specified, so "" is used.
If 3 then first check if the %macro-name% syntax is found in the 'replacement text' string and search the user's macros for a match. If a match is found, the 'replacement text' becomes the 'gcode' content of the macro, if no match, use the replacement text as-is.
It is most commonly expected that the "regex to match" will match and thus replace the whole line, however, note that the "regex to match" may match only a portion of the gcode line, and the replace with functionality only changes the matched text, leaving the remainder of the line unaltered.

The following now all work;

M6T1 in code, "M6T[0-9]+" enabled will REMOVE M6T1 as per original functionality
M6T1 in code, "s/M6T[0-9]+" enabled will REPLACE M6T1 with "" as no replacement text was specified
M6T1 in code, "s/M6T[0-9]+/G21" enabled will REPLACE M6T1 with G21 if that is what the user desires
M6T1 in code, "s/M6T[0-9]+/%1%" enabled will REPLACE M6T1 with whatever macro "1" is defined as by the user in the Gcode column. User must be aware that the result from macro "1" will be passed through as-is.
M6T1 in code, "s/M6T[0-9]+/%Macro #1%" enabled will REPLACE M6T1 with whatever macro "Macro #1" is defined as by the user in the Gcode column. User must be aware that the result from macro "Macro #1" will be passed through as-is.
All REMOVES or REPLACES are logged under INFO to assist user debugging regex and %macro% settings.

Confirmed working (Apple and RPi). Core algorithm re-written to reduce if nesting depths.

Found a typo in jog service.java where getStepSizeZ() was errantly against multiplyABCStepSize(), should have been getStepSizeABC(), which is corrected.

Confirmed working (Apple and RPi).
