tdf#152724 Extend ODF for blank width "_x"

Number format code "_x" is currently saved as a text string containing a
number of spaces corresponding to the width of character "x". It may be
confusing for user if its format code is modified.
This change introduces a new XML tag XML_BLANK_WIDTH_CHAR to replace the
previous text string if ODF version is extended

<number:text> and <number:embedded-text>:
the attribute is composed of a string containing the used character and its
position in the text string (if position is 0, it is omitted).
Several blank code characters are separated by '_'.
Replacement blanks in the text string are preserved to enable compatibility.

Example: format code
"foo"_M_I_N"!"???,???.000_.000"!"_)
is saved as:
<number:number-style style:name="N173">
<number:text loext:blank-width-char="M3_I6_N7">foo       !</number:text>
<number:number number:decimal-places="6" number:min-decimal-places="6" number:min-integer-digits="6" loext:max-blank-integer-digits="6" number:grouping="true">
<number:embedded-text number:position="-4" loext:blank-width-char="."> </number:embedded-text>
</number:number>
<number:text loext:blank-width-char=")1">! </number:text>
</number:number-style>

Add QA test
