patch from XhmikosR:
bump the copyright year, remove unwanted spaces and convert some tabs to spaces.

Use CAppUtils::SearchReplace() to replace the variables since that function replaces all occurrences and not just the first.
(Fixes issue #349) : %project replacement is executed only for the first occurence in script/command

Improve the regex to check whether an url points to a real repository and not a page generated by SVNParentPath.
(Fixes issue #341) : Some SVN url creates never ending list of sub-projects

(Closes issue #293) : Adding %username to command execution

Reduce stack size by allocating memory on the heap.

(Closes issue #321) : Option to disable popup notifications

If modifying the sys tray icon fails, remove it and add it again just to be on the safe side.

* only save the urls file if something important changed during an update check
* do not read the urls file for every update check but create an in-memory copy instead

Closes issue #304

Rename a lot of classes and methods.

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