Rename msysGit installer to msysGit-fullinstall

While at it, adjust it to grok the html submodule, be nice to
the root directory name "msysgit" (instead of "msysGit"), and
remove any existing archive of the same name (as 7-Zip cannot
update files which are already in the archive).

msysGit-netinstall: if all else fails, try an HTTP proxy

The last strategy after trying git:// and http:// protocol is to
ask the user to type in an HTTP proxy.  If this fails, all hope is
lost.

Update module git and change date in release notes.
HowToRelease.txt: Make filename camel-case
WinGit: Improve error handling and fix hard link creation

Several return values have not been checked so far, this has been fixed.
Moreover, all error message boxes now print the corresponding source code
line number.

Existing files are now deleted before a hard link with the same name is
created. This should fix some hard link creation errors reported to the mailing
list. If hard link creating fails, built-in aliases are now created as copies
as a fallback.
WinGit: Log all errors that are shown as message boxes
WinGit: Be less verbose when packaging the installer

The names of the processes files are not printed to STDOUT anymore to make it
easier to find any error messages.
WinGit: Remove reference to cpio, as it does not exist anymore
Add a script to make an msysGit shortcut

You can use the script /share/msysGit/add-shortcut.tcl to create an
msysGit shortcut.  The following arguments are handled:

q	QuickLaunch (default)
d	Desktop
s	StartMenu (TopLevel)
s2	StartMenu (Programs>msysGit>msysGit)
a	All Users' StartMenu (TopLevel)
a2	All Users' StartMenu (Programs>msysGit>msysGit)

(This reinstates the program create-shortcut in /share/msysGit which
was removed from /share/WinGit in favor of the InnoSetup based
installer.)

WinGit: Fix uninstall check regarding ssh-agent.exe

Do not fail uninstall anymore if ssh-agent.exe does not exist, and restore
ssh-agent.exe (which is deleted as a test if it is running) in case uninstall
is aborted by the user by choosing "no" in the initial "Are you sure?"-style
dialog.
WinGit: Do not fail hard link creation when previous file does not exist

Fix a bug that prevented hard link creation (and used the fallback to copy
the files instead) when deleting any previous file with the target name of the
hard link failed because the file did not exist.
WinGit: Do more verbose logging during built-in creation
WinGit: Add again more verbose / additional log messages for built-in creation
Add note about spurious crashes related to Logitec to ReleaseNotes
