[GITEA] Improved Linguist compatibility

Browse source 
Recognise the `linguist-documentation` and `linguist-detectable`
attributes in `.gitattributes` files, and use them in
`GetLanguageStats()` to make a decision whether to include a particular
file in the stats or not.

This allows one more control over which files in their repositories
contribute toward the language statistics, so that for a project that is
mostly documentation, the language stats can reflect that.

Fixes #1672.

//
// - `.gitattributes` is empty, so `isDetectable.IsFalse()`,
// `isVendored.IsTrue()`, and `isDocumentation.IsTrue()` will be
// false for every file, because these are only true if an
// attribute is explicitly set.
//
// - There is `.dot.pas`, which would be considered Pascal source,
// but it is a dotfile (thus, `enry.IsDotFile()` applies), and as
// such, is not considered.
//
// - `some-file.xml` will be skipped because Enry considers XML
// configuration, and `enry.IsConfiguration()` will catch it.
//
// - `!isVendored.IsFalse()` evaluates to true, so
// `analyze.isVendor()` will be called on `cpplint.py`, which will
// be considered vendored, even though both the filename and
// contents would otherwise make it Python.
//
// - `!isDocumentation.IsFalse()` evaluates to true, so

// be considered documentation, thus, skipped.
