Override book's title if Title is set in XML

[vinhtq115]

In ComicRack XML Schema, there is a Title field that is not being used by KCC. In this PR, I changed so that if this field is set, it will automatically be used.

Also, pyinstaller is added to requirements.txt for building on M1 to avoid pyinstaller: command not found.

Thanks for your PR.

imho, we shouldn't add pyinstaller to requirements.txt
It is only needed for building an executable.
It is not needed when using the project from source
and in docker images, for example, it would add unneeded dependencies.

I have removed pyinstaller from requirements.txt. Since the building instruction for M1 did not mention about pyinstaller and appdmg, I suggest adding a Wiki page for users who want to build the binary themselves.

@darodi I have updated the wiki page to be more specific.
