File Browser: Scroll view with arrow keys navigation

Adjusts view to display active file after using arrow keys to navigate through files.

Correction to previous commit

Fix file key select using wrong file after border select in scrolled view

Basically, after border selecting, a wrong file was selected by using arrow keys if the screen was scrolled a bit vertically. Reason was that we didn't use correct view space coordinates but region space coordinates for measuring distance from mouse to first/last file in selection after border select.

Fix T46155: Sequencer Text Effect: wrong vertical 'TOP' alignment.

Logic was broken for this vertical alignment option - we need to remove one line height here...

Fix T46030: Strange behavior of Cycles Brick Texture

Added some extra seed to the hash, so it's now less likely to give repetitive
patters at values around zero.

This will change distribution of bricks for existing files. but it's something
inevitable.

Image Stamp: word-wrap support for 'note' text

Sequencer: word-wrap support for sequencer text

Also add vertical alignment option,
default align to bottom for subtitles.

UI: word-wrap support for tooltips

Tooltips will automatically wrap when exceeding UI_TIP_MAXWIDTH.

BLF: initial word-wrap support

- Adds support for word wrapping to Blender's BLF font library.
- Splits lines when width limit is reached or on explicit n newlines.

Details:

- Word wrapping is used when `BLF_WORD_WRAP` flag is enabled.
- There is a single loop to handle line wrapping,
this runs callback, passing in a substring,
this way we can avoid code-duplication for all word-wrapped
versions of functions... OR... avoid having to add support
for word-wrapping directly into each function.
- The `ResultBLF` struct was added to be able to get the number
of wrapped lines, when calling otherwise unrelated functions
such as `BLF_draw/BLF_width/BLF_boundbox`,
which can be passed as the last argument to `BLF_*_ex()` functions.
- The `ResultBLF` struct is used to store the result of drawing
(currently only the number of lines wrapped, and the width).

Doc: remove todo's from BMesh code

These were out of date and better have outside the source.

Also clarify BMLoop description.

Minor edits to sys-info

- remove byte b''
- remove always false check for missing buildinfo.
- use textwrap module

Cycles: simplify logic for calculating dof-dist

Matches change from BKE_camera

Use squared length where possible

Fix UI crash entering very long strings

Strings exceeding UI_MAX_DRAW_STR weren't null terminated.

Fix T46148: Sculpt view-clip fails in ortho mode

Cleanup: simplify PyBMesh customdata API use

Cleanup: remove unused WriteFile members

Support relative frames w/ start/end args

Address request from T46136: make softrange for 'simple deform' angle from -360 to 360 degrees...

This should be safe enough for final 2.76, sould we make other RC.

Doc: escape enum name & description

Needed since key enum now uses many characters as they're typed.
