More rsid

The main functionality of rsid is now ready.You can download a patch with the current changes here.

I had to handle the various ways text can be inserted in the document since every time different functions are called (e.g. when just writing text, pasting it from the same document, pasting from an external source and splitting a paragraph in two.).

Rsids are now being saved as 32 bit hexadecimal numbers in the content.xml of the document, and, following the OOXML standard, each rsid is greater than the previous (the one generated in the previous session). The session rsid as well as the root rsid (the one generated when the original document was created) are saved as document settings in the settings.xml (they are not yet in hex).

Here is an example of how it works:

I created a document with the following text:

This is the original text of a document that has three paragraphs.
Here is the second paragraph of the original text.
Here is the third paragraph of the original text.

And this is the content.xml:

[...]
<office:automatic-styles>
<style:style style:name="T1" style:family="text">
<style:text-properties style:rsid="000134cc"/>
</style:style>
</office:automatic-styles>
<office:body>
<office:text>
[...]
<text:p text:style-name="Standard">
<text:span text:style-name="T1">
This is the original text of a document that has three paragraphs.
</text:span>
</text:p>
<text:p text:style-name="Standard">
<text:span text:style-name="T1">Here is the second paragraph of the original text.</text:span>
</text:p>
<text:p text:style-name="Standard">
<text:span text:style-name="T1">Here is the third paragraph of the original text.</text:span>
</text:p>
</office:text>

in the settings.xml I have the following two lines:

<config:config-item config:name="Rsid" config:type="int">79052</config:config-item>
<config:config-item config:name="RsidRoot" config:type="int">79052</config:config-item>

Then I split the third paragraph:

This is the original text of a document that has three paragraphs.
Here is the second paragraph and some text from the second session of the original text.
Here is the third paragraph
of the original text.

[...]
<office:automatic-styles>
<style:style style:name="P1" style:family="paragraph" style:parent-style-name="Standard">
<style:text-properties style:rsid="000134cc"/>
</style:style>
<style:style style:name="T1" style:family="text">
<style:text-properties style:rsid="00202baa"/>
</style:style>
</office:automatic-styles>
<office:body>
<office:text>
[...]
<text:p text:style-name="P1">
This is the original text of a document that has three paragraphs.
</text:p>
<text:p text:style-name="P1">
Here is the second paragraph
<text:span text:style-name="T1">and some text from the second session</text:span>
of the original text.
</text:p>
<text:p text:style-name="P1">Here is the third paragraph </text:p>
<text:p text:style-name="P1">
<text:span text:style-name="T1">of the original text.</text:span>
</text:p>
</office:text>

and in the settings:

<config:config-item config:name="Rsid" config:type="int">2108330</config:config-item>
<config:config-item config:name="RsidRoot" config:type="int">79052</config:config-item>

Finally, I copied some text from the first two paragraphs and pasted it in the middle of the third:

This is the original text of a document that has three paragraphs.
Here is the second paragraph and some text from the second session of the original text.
Here is the original text of a document that has three paragraphs.
Here is the third paragraph
of the original text.
