* Fix keywords in comments being highlighted
* Highlight Nim's escape sequences for strings
* Highlight common comment tags
* Add on/off to the highlighted boolean values
* Remove redundant regex highlighter for comments
* Fix autoindent indenting lines more than it should
Before:
```nim
type
MyType = tuple
myint: int # This line needs to be indented manually
```
After:
```nim
type
MyType = tuple
myint: int # Lines after 'tuple' are now indented automatically
```

Falls back on old mechanism if `XDG_RUNTIME_DIR` is not set.
The ability to specify a session as "<user>/<name>" was removed, since
it isn't possible to compute the value of `XDG_RUNTIME_DIR` for another
user, we wouldn't have access to it if we could, and it would be awkward
to support this feature only when `XDG_RUNTIME_DIR` is unset. Also,
`rename-session` did not work when another user's session was specified.
Closes#3019
Make sure decorators are on their own line, and don't stop highlighting at
the first dot when they are imported, e.g.
```
import enum
@enum.unique
class A(enum.Enum):
…
```
Ideally highlighting shouldn't stop at the first parenthesis either
(e.g. `@foo(['1'])`), but the current code somewhat highlights the contents
of the parens already, which is good enough in most cases.
This commit implements formatting behaviour when the first character of a
docstring is a newline. In that case, the exact indentation level of the
next line will be removed from that line and all subsequent non-empty lines.
An error will be returned if a subsequent non-empty line does not have the
same indentation level.
The docstrings are always trimmed (surrounding whitespaces) whether the
first character is a newline or not, as was the case prior to this commit.
Example: the following declaration
```
define-command test -docstring %{
test: do something
Nothing really.
More
indented
lines.
} nop
```
would be rendered as
```
test: do something
Nothing really.
More
indented
lines.
```
