Error logging for various file operaitions. This will help a lot if some...

...one looks into the log of a deployed instance.

(I'm tracking down an issue where both on my Win 8.1 dev box and both on a Server 2012 box, where GitCandy cannot create a repo when it is deployed. With theses error logging I'm investigating this:

04/11/2015 13:46:37.964 -07:00 Error, LibGit2Sharp.NameConflictException: Failed to make directory 'c:/Users/Csaba/Documents': Cannot create a file when that file already exists.

at LibGit2Sharp.Core.Ensure.HandleError(Int32 result)
at LibGit2Sharp.Core.Proxy.git_repository_init_ext(FilePath workdirPath, FilePath gitdirPath, Boolean isBare)
at LibGit2Sharp.Repository.Init(String path, Boolean isBare)
at GitCandy.Git.GitService.CreateRepository(String name)

My Repositoriesdirectory settings points to c:/Users/Csaba/Documents/GCD/Repositories/ and when I start GitCandy from debugger in an IIS Express, it works.)

My purpose of updating was that libgit2/libgit2sharp#795 is mysteriously looks like the same what I experience. And that issue was fixed in libgit2, and thus in LibGit2Sharp. So for the upgrade didn't solve my problem. See also this SO entry downvoted by some smart asses: https://stackoverflow.com/questions/29583302/gitcandy-cannot-create-repository-when-it-is-deployed

I can't reappear this problem in my environment, even though, I believe lg2s has been improved for this kind of problem, and we need update GitCandy nothing. So, please update lg2s to latest version. Just modify long size = 0; -> var size = 0L; on here

By the way, please merge logs into one line just like Logger.Error("Something: " + ex) and reverse the count of retrying.
