Extends support application id and secret support

[AmonRaNet]

With this pull request grive2 will have more advanced support of the custom client id and secret.

• cmake: projects supports custom id's during cmake config (see README)
• client id and secret always saved in .grive config file after grive -a
• new CLI option added grive -a --print-url which will return generated url for token request

Small changes:

• cmake: GRIVE_VERSION is cached and can be overwritten during cmake config

Probably repeats partially #242

I've created my id and secret using google's console and compile the last commit but when I put my "key" from the Google's page, I've the following error (console):

I found interesting fact: grive not refreshing config ".grive" file when you try to auth in same folder again. If you trying to use same gdrive folder for sync - first delete old .grive, then run grive -a.

Other aspect it is google account themselves. Please check Google API enabled, access rights.given.
