Extend tutor file (#2133)

Browse Source 
* Adds tutorial sections for multiple areas including:
- Changing selections to uppercase / lowercase
- yanking and pasting
- macros
- selecting to chars with t and f

PS: I got kind of carried away and put off commiting for a while,
    will commit to commit more often in the future.

* Changed section titles to all uppercase

* Added recap and section about jumplist

* Added sections for searching in file, joining lines and indenting lines.

* Removed some trailing whitespace

* Evened out the space between sections to all be 5 lines

* Add section on opening lines (o) and recap

* Changed the amount of lines between sections

This is so that - on a 24 line terminal -
only one section is visible at a time and
page up/page down goes straight to the next
section keeping the header at the top.

* Punctuation error

- "Type" for multiple keypresses / modifiers
- "Use" when referencing two inputs as a pair.

* till not 'til

* Say 'press' instead of 'type' when referring to symbols

* 'outdent' not 'unindent'

* Typo and grammar.

* Replace all 'press's with 'type's (apart from places it would make no sense in).

* Improve examples for joining and indenting lines.

* Section alignment.

Type C-i and C-o to move forward and backwards in the jumplist
