Saves every file of the lambda as a new version

files is the whole lambda, lambda.cs first: a file the newest version has and this request does not is not in the new version. To change a few files, POST …/versions/changes sends only those.

A file name may be refused - a C# file has to be named as C# names its files, a resource needs an extension, and no name may hold spaces or be one Windows reserves; the message says what is wrong with which. The files together may not come to more than the tier of the lambda allows a version (see the limits). Whether the code compiles is not checked unless it is deployed: POST …/code/check compiles it without saving.
