commitmonitor Code

Merge the MultiSCCS branch to trunk and fix some minor merge conflicts.

Accurev base implementation (tested only with Accurev v4.7.1)
- Abstracted SVN calls to a 'SCCS' API
- Implemented basic version of this API for Accurev (v4.7.1)
- Modified OptionsDlg to specify Accurev parameters
- Modified URLDlg to add option to select which SCCS to use, and enter Accurev parameters

Big TODOs
- Replace ugly parsing with XML parser
- Clean up implementation of diff for Accurev
- Move starting of diff to background loop
- Make use of already existing diff parameters
- Implement missing features, or disable them at least in Accurev mode
- Update CommitMonitor_VS10.sln (I do not have access to VS2010)

Update the versions file for the update check.

Tag the 1.7.0 release.

Bump version number to 1.7.0

Set the XML_STATIC param also for the svn and neon build since they include expat.

Use the new header from apr.

Don't build expat separately from apr-util but include it in the apr-util build.

Update the version resource for SASL.

Update libraries:

* zlib to 1.2.5
* svn to 1.6.13
* apr to 1.3.12
* apr-util to 1.3.10
* neon to 0.29.5
* sasl to 2.1.24RC1
* sqlite to 3.7.3
* upx to 307
